Abstract

In recent years, the construction industry has been faced with a decline in the availability of natural sand due to the growth of the industry. On the other hand, the metal casting industries are being forced to find ways to safely dispose of waste foundry sand (FS). With the aim of resolving both of these issues, an investigation was carried out on the reuse of waste FS as an alternative material to natural sand in concrete production, satisfied with relevant international standards. The physical and chemical properties of the FS were addressed. The influence of FS on the behaviour of concrete was evaluated through strength and durability properties. The test results revealed that compared to the concrete mixtures with a substitution rate of 30%, the control mixture had a strength value that was only 6.3% higher, and this enhancement is not particularly high. In a similar manner, the durability properties of the concrete mixtures containing FS up to 30% were relatively close to those of control mixture. From the test results, it is suggested that FS with a substitution rate of up to 30% can be effectively used in concrete production without affecting the strength and durability properties of the concrete.

1. Introduction

The rapid advance of globalization and the growth in the population has resulted in a growth in building construction that has consequently led to a higher demand for construction materials. River sand is one of the main ingredients used as a fine aggregate in concrete production. A rising demand for construction material has led to the overexploitation of river sand, and this overexploitation has led to harmful consequences like increase in river bed depth, lowering of the water table, and intrusion of salinity into the river. In addition, the restriction in the extraction of sand by government organizations has increased the price of sand, severely affecting the stability of the construction industry [1]. For this reason, finding an alternative material to sand has become vital. Over the last several decades, an enormous amount of research has been carried on the use of industrial waste, including granite and marble waste [2–7], tire waste [8], palm oil ash [9], timber waste [10], and also marine sand [11] as a substitute/replacement material for fine aggregate. From the research outcomes, it was suggested that the substitution of industrial waste as an alternative material in concrete making could improve the structural properties of concrete and promote sustainable concrete development. Foundry sand (FS) is a high silica content sand material which is a by-product from the metal alloys casting industries [12]. In foundries, superior silica sands are bonded with clay or chemicals and used for the material molding and casting process. Foundries recycle the sand as many times as possible, and when the sand is no longer recyclable, then it is disposed of; this is called foundry sand [13]. About 15% of the sand utilized in casting production is ultimately disposed of by the foundry industry, amounting to millions of tons. In India, many foundry industries are dumping this waste in nearby vacant areas, which is creating an environmental problem. In Coimbatore, Tamilnadu, India, many residential areas are established over landfills, which are basically composed of FS from ferrous and nonferrous industries. Landfill is an incorrect option, because the embodied energy in FS is not used and will create soil contamination [14].

Over the last several decades, FS has been reused as a subgrade material [15] in highway and soil stabilization application [16]. However, the waste that is reutilized in this way very is negligible, and the practice presents the risk of leaching intrusion. Very recently, research has been carried out on the reutilization of FS as substitute material in concrete and concrete related products. A marginal increase in the strength properties can be achieved by the inclusion of UFS as partial replacement for fine aggregate in concrete making [13]. The replacement of 10% aggregates with waste foundry sand was suitable for asphalt concrete mixtures, and the substitution did not significantly affect the environment around the deposition [17]. FS is a viable means of producing economical self-compacting concrete (SCC) by using FS substitution; however, further research is needed to develop the optimum FS proportion [18]. The substitution of foundry sand in concrete reduces the voids in concrete and has helped to spread the C–S–H gel widely in the concrete [19]. The Inclusion of FS as a sand replacement significantly improved the abrasion resistance of concrete at all ages because of the formation of a denser matrix [20]. FS can be effectively utilized in making good quality RMC as a partial replacement for fine aggregates with no adverse mechanical, environmental, and microstructural impacts; however, the replacement should not exceed 20% [21].

It can be understood that a great deal of research has been carried out on the reuse of FS in civil engineering application. However, limited research has been focused on the use of FS in concrete production, and more research is also needed to develop the most favorable replacement of FS in concrete production. With this aim, the main objective of this experimental investigation is to examine the potential reuse of FS obtained from an aluminium casting industry, Coimbatore, in Tamilnadu, India, as a replacement for fine aggregate in concrete production, at different substitution rates. The effect of FS substitution on the mechanical properties of concrete was examined. In addition, the influence of FS on the durability properties of concrete was also evaluated in order to ensure the reliability of its usage in aggressive environments. Based on the results of the mechanical and durability tests, the most favorable proportion of FS in concrete production was established.

2. Experimental Program

2.1. Materials

Locally available ordinary/commercial Portland cement was used in this study as a binding material. The specific gravity of the cement was tested according to IS 8112:2013 [22] and the value obtained was about 3.14. The chemical properties of the cement were tested according to IS 4032:1985 [23], and the results were summarized in Table 2. The river sand passing through 4.75 mm was used as fine aggregate. Locally available 20 mm size blue metal jelly was used as a coarse aggregate. The specific gravity [24] of the sand and the coarse aggregate was about 2.48 and 2.67, respectively. According to IS 2386:1963 [25], sieve analysis was carried out on both fine and coarse aggregate. Foundry sand (FS) obtained from an aluminium casting industry, Coimbatore, in Tamilnadu, India, was used in this study and the FS is shown in Figure 1. It is a green sand (clay sand); clay was used as a binder material. The physical and chemical properties of the FS were tested according to Indian standards and they were listed in Tables 1 and 2, respectively. The specific gravity and density [24] of the FS were about 2.24 and 1576 kg/m³, respectively. The water absorption [26] of the FS was about 1.13%, which is higher than that of normal sand due to the presence of ashes and wood particles. Sieve analysis was carried out to understand the grain size distribution of the FS (see Figure 2), and it was observed that 8% of FS were less than 75 μm, which show that the FS is fineness material. The chemical properties of the FS were tested according to IS 4032:1985 [23], and the results obtained showed that FS contains about 87.48% silica (SiO₂) and 4.93% alumina (Al₂O₃). The results of the chemical analysis indicated that FS is a very suitable material for concrete production.

2.2. Concrete

Concrete mix proportions were designed to achieve the strength of M25, according to IS 10262:2009 [27]. The concrete mix proportion was 1 : 1.53 : 2.86. A constant water to cement ratio (W/C) was followed for all mixtures, and the value was about 0.44. Of the six mixtures, five mixtures were prepared by replacing 10%, 20%, 30%, 40%, and 50% of natural sand with FS, and the one remaining mixture was a control mixture (CM) that did not use FS. The detailed formulation of the proportions of six mixtures was given in Table 3.

2.3. Specimen Preparation

The concrete mixtures were prepared with and without FS substitution. The FS substitution rate was varied between 10% to 50%, in increments of 10%. FS was washed with fresh water more than four times before it was used in the concrete to remove the ashes and clay particles. Then it was dried in atmospheric sunlight for the duration of two days and then used in concrete mixtures. For all mixtures, the aggregates such as cement, natural sand, coarse aggregate, and FS were weighed in a dry condition and were mixed together in a laboratory batch mixer in order to avoid aggregate and water loss. The properties of the fresh concrete, such as its workability, were measured by the slump cone test. To determine the compressive strength and tensile strength of the concrete, cubes and cylinders with a size of 150 mm × 150 mm × 150 mm and 150 mm × 300 mm were prepared. Beams having a size of 100 mm × 100 mm × 500 mm were also prepared to evaluate the flexural strength of the concrete. All the specimens were filled with concrete in three layers, and each layer of the concrete was effectively compacted by table vibrator [28]. After casting all specimens, the specimens were covered with a plastic sheet in order to avoid moisture loss. After that, specimens were kept at room temperature for 24 hrs and thereafter were demoulded and transferred to the curing tank until their testing dates. After the required curing days, the cubes were tested in a compression testing machine (CTM) having a capacity of 2000 kN at the ages of 7, 28, 90, and 180 days. The cylinders and beams were tested in the CTM and flexural testing machine, respectively, at the ages of 28, 90, and 180 days to evaluate the tensile and flexural strength of the concrete [28]. All specimens were tested according to the Indian standards [29]. According to the procedure described in ASTM C1202-97 [30], the chloride permeability test was conducted on all concrete mixtures, and resistance to the penetration of chloride ions was measured by determining the electrical conductance of concrete. A concrete disc having 102 mm diameter and 51 mm thickness was prepared and allowed to cure until the testing dates. Afterwards, both ends of the disc were sealed with cell, one of which was filled with 3% NaCl solution, while the other was filled with 0.3 N NaOH solutions. A potential difference of 60 V was maintained across the two cells and the amount of charge passed to the specimen was monitored for the duration of 6 hrs. The amount of chloride penetration was measured in terms of Coulombs [11]. According to IS 3085:1965 [31], the water permeability of the concrete was determined and the concrete permeability test apparatus was used in this study to determine the water permeability. By measuring the water volume that passes through the specimen under constant air pressure 10 kg/cm², the water permeability of the concrete was obtained. Concrete cylinders having a size of 150 mm × 300 mm were prepared for the carbonation test. After curing days, all the specimens were air cured for the duration of 90 days and 180 days and then they were split. The split surface of the concrete was thoroughly cleaned and the phenolphthalein indicator was uniformly applied along the entire length using a brush. The average depth was measured at three points to the nearest 1 mm, from the external surface to the colorless phenolphthalein region [11]. The electrical resistivity of the concrete was determined using a concrete electrical resistivity meter, under saturated condition. Concrete cubes having a size of 150 mm × 150 mm × 150 mm were prepared in all mixtures for sulphate resistance test. The cubes were immersed in a solution containing 7.5% NaSO₄ and MgSO₄ by weight of water, for the duration of 180 days and 365 days. The sulphate resistance of the concrete mixtures was evaluated by measuring the compressive strength of the immersed cubes at the age of 180 days and 365 days. To discuss the mixtures easily, names were given to the mixtures, such as CM, FS 10%, FS 20%, FS 30%, FS 40%, and FS 50%. For example, the name FS 20% indicated that the concrete mixture contained 20% foundry sand.

3. Result and Discussion

3.1. Fresh Concrete Properties

The workability of the concrete was measured through the slump cone test apparatus at times ranging from immediate after mixing, after 30 minutes and after 60 minutes. The results revealed that the substitution of FS decreases the workability of the concrete; furthermore, an increase in the substitution rate decreases the workability of the concrete further [28], as shown in Figure 3. However, close observation of Figure 3 shows that the influence of FS on the workability of the concrete was profound when the substitution rate was beyond 30%, and, in addition, the slump value of the mixtures FS 30% was relatively equal to the CM. The decrease in the workability of the concrete with the substitution of FS may be attributed to the fineness and high water absorption properties of the FS. The fineness and high water absorption of the FS increases the water demand of the concrete by water absorption, resulting in decreased workability. The workability of the concrete was decreased as time elapsed; however, the slump loss of FS mixtures was high when compared to the CM. The fineness of the FS increases the surface of hydration products, leading to greater water absorption. From the observation, it was observed that modification of the water content should be applied to the mixtures based on the fineness of the substitution material [28].

3.2. Mechanical Properties

3.2.1. Compressive Strength

The compressive strength of all mixtures was obtained at ages of 7, 28, 90, and 180 days, and the values are summarized in Table 4 and presented in Figure 4. The main objective of this research is to utilize FS as a substitute material in concrete production and not to enhance the strength properties of the concrete. As expected, it was observed that even though no improvement in strength was observed in FS concrete, the compressive strength of the concrete mixture FS 30% was probably equal to the strength value of the control concrete (CM). Compared to mixture FS 30%, control mixture has shown 5.7% higher compressive strength at the age of 28 days; in addition the similar difference was observed at the ages of 180 and 365 days. However, mixtures FS 40% and FS 50% were shown to have lower strength compared to the CM mixture at the age of 28 days, and, furthermore, showed a poor enhancement in strength upon aging when compared to the other mixtures. The certain properties of FS such as fineness and high water absorption decrease the compressive strength of the concrete. The fineness and high water absorption of the FS creates water demand in the concrete, causing poor workability and leading to a decrease in the compaction of the concrete, resulting in the formation of higher number of small pores close to the aggregate surfaces. The other possible factor is that the presence of clay, sawdust, and wood flour results in a reduction of the specific density of the material and also decreases the density of the concrete by creating air voids in the concrete [28]. The compressive strength of the concrete upon aging was determined by using (1), recommended by ACI 209 (ASTM Type 1) [32]. Consider the following:where is the mean compressive strength at the age of days, is the mean compressive strength at 28 days, and is the age of the concrete in days. The calculated compressive strength values of the concrete are listed in Table 4. The correlation made between the measured and calculated compressive strength of the linear regression line was shown to be strong as shown in Figure 5.

3.2.2. Flexural and Split Tensile Strength

The flexural and split tensile strength of all concrete mixtures were measured at the ages of 28, 90, and 180 days. Like compressive strength, up to a substitution rate of 30% the flexural and tensile strength of the concrete mixtures was relatively equal to the strength value of the CM. For instance, the flexural strength of the mixtures FS 30% was about 3.879 N/mm², whereas the control mixtures achieved the strength of about 4.087 N/mm², which is only 3% higher than that of mixtures FS 30%. At the age of 28 days, compared to FS 10%, FS 20%, and FS 30% mixtures, mixture CM showed tensile strength that was 4.53%, 6.03%, and 7.08%, respectively, higher and this difference in strength is not relatively high. A similar difference was observed in both the flexural and split tensile strength of the concrete at the ages of 180 and 365 days. The flexural and tensile strength of the mixtures with the substitution rate up to 30% was increased upon aging; however, this behaviour was not observed in the FS 40% and FS 50%. This is a result of the increase in the continuous porous system, resulting in a poor denser matrix due to the fineness and the presence of dust particles of the FS [28]. Compared to FS 40% and FS 50% mixtures, the mixture CM showed a tensile strength of 16.38% and 19.32%, respectively, higher. Based on (2) suggested in IS 456:2000 [33], the flexural strength of the concrete was estimated from the compressive strength obtained. Consider the following:where is the flexural strength of the concrete and is the compressive strength of the concrete. The correlation between the measured and computed flexural strength was quite strong, as shown in Figure 6, and the mean value was 0.9799. The split tensile strength of the concrete was evaluated from the obtained flexural strength value based on (3), recommended in the CEB-FIP Model Code:1990 [34]. Consider the following:where is the depth of the beam in mm and has the value of 100 mm. The strengths obtained are expressed in N/mm². The correlation between the measured tensile strength and the tensile strength calculated using linear regression analysis was strong, as shown in Figure 7. Based on the experimental split tensile strength obtained, the relation between the compressive strength and tensile strength was found and expressed in the following:where is the split tensile strength of the concrete and is the compressive strength of the concrete.

3.2.3. Elastic Modulus

The dynamic elastic modulus of the concrete was determined using (5), recommended in 13311:1992 [35] and IS 452:2000 [33], from the ultrasonic pulse velocity (UPV) and compressive strength values obtained at the age of 28, 90, and 180 days. Consider the following:where is the dynamic Young’s modulus of elasticity (Mpa) and is the compressive strength of concrete, is the density of concrete in kg/m³, is the pulse velocity in m/second, and is the dynamic poissons ratio of the concrete. The difference between the calculated elastic modulus values was not great and the values were relatively close, as shown in Figure 8.

3.3. Durability Properties

3.3.1. Rapid Chloride Ion Penetration (RCPT) Test

The service life of reinforced concrete structures generally depends upon the capacity of the concrete to resist chloride ion penetration. RCPT test was thus conducted on all mixtures at the ages of 180 and 365 days, according to the procedure described in ASTM C1202-97 [30], and the results were compared with the penetration limits suggested in ASTM C1202-97 [30]. The resistance of all mixtures to chloride penetration is shown in Figure 9 and listed in Table 5. From Figure 9, it can be understood that the substitution of FS in concrete increases the chloride penetration value of the concrete, and the increase in penetration was directly proportional to the FS substitution rate. However, the penetration values of the mixtures with a substitution rate of up to 30% was moderately equal to the penetration value of the CM. The penetration value of the FS 30% was 621 coulombs at the age of 180 days, whereas the control mixture achieved a penetration value of 420 coulombs, which is only 32.36% lower than that of mixture FS 30%. However the penetration value of the FS 30% is much lower than the maximum value recommended in ASTM C1202-97 [30]. The same difference in penetration value was observed at the age of 365 days. In general, the resistance to chloride penetration is higher, when the formation C₃A in the binder is higher. The FS used in this study contains 4.93% of Al₂O₃, which is relatively equal to the cement. Even though the presence of SiO₂ and Al₂O₃ in the FS may form the denser tricalcium aluminates (C₃A), the poor workability of the concrete due to the fineness of FS, resulting in poor compaction of the concrete, led to a continuous porous microstructure. The other possible factor was that the presence of the wood and flour particles caused the formation of air voids in the concrete. In general, penetration has occurred along the water paths or open pores. The formation of this continuous pore system promoted the penetration of chloride ions. Mixtures FS 40% and FS 50% showed significantly higher chloride penetration compared to the CM. On the whole, the substitution of FS in concrete has a profound effect on the chloride penetration; however, this effect was not significant up to a substitution rate of 30% and the penetration value was confirmed as being “very low” at both ages of concrete.

3.3.2. Water Permeability

According to the procedure described in IS:3085-1965 [31], the water permeability test was performed on all concrete mixtures at the age of 180 and 365 days. The test results obtained were presented in terms of permeability coefficient (see Table 5) by using (6) suggested in IS:3085-1965 [31]. Consider the following:where and represent the quantity of water in millimeters and the area of the specimen face in cm², respectively. and are the time in seconds and the ratio of the pressure head, respectively. Like RCPT, the results revealed that the permeability of the concrete increased when the substitution rate was increased; however, the influence was significant beyond the substitution rate of 30%. The correlation between the water permeability and RCPT charges was shown to be quite strong, as can be seen in Figure 10. ACI 301-89 [11] recommended the maximum permeability coefficient value of 15 × 10⁻¹² m/s. The permeability coefficient value of CM was about 5.9 × 10⁻¹² m/s at the age of 180 days, whereas the FS 30% mixture showed a coefficient value of 7.2 × 10⁻¹² m/s, which is significantly lower than the maximum permeability coefficient value recommended in ACI 301-89 [11]. On the whole, the substitution of FS does not have a significant effect on water permeability up to a substitution rate of 30%.

3.3.3. Carbonation Depth

Carbonation of concrete is one of the critical parameters associated with the corrosion of steel reinforcements. For all mixtures, carbonation depth was measured at the ages of 180 and 365 days and summarized in Table 5. The obtained results in terms of carbonation coefficient () value using (7) [19] are presented in Figure 11. To compare the carbonation resistance, (7) is generally used, suggested by many researchers [19]. Consider the following:where is the carbonation coefficient (mm/year^0.5), and and are the carbonation depth in mm and period of exposure in years, respectively. The results demonstrated that the carbonation depth of the concrete increases with the increased substitution rate; in addition, the increase in depth was significant beyond the substitution rate of 30%. Compared to mixture FS 30%, control mixture has shown their resistance to carbonation by only 38.89%, higher, which is not relatively high, and the difference is acceptable. Similar behaviour was observed by Siddique et al., 2011 [19]. Close observation of Figure 11 shows that the increase in carbonation depth with reference to the increase in the FS substitution rate was not linear. For the substitution rate of 20%, the increase in carbonation depth value was 0.96 mm with reference to FS 10%; however, for the substitution rate of 40%, the increase in carbonation depth value was 1.73 mm with reference to FS 30%. The increase in carbonation depth when the FS substitution rate is increasing can be attributed to the poor workability of the concrete, which resulted in poor compactness and led to the continuous porous system. The other reason is the presence of the carbon content in the FS. Usually, carbon does not react with water under normal conditions. But under more forcing conditions, it may react with the water and produce CO, and this reacts with calcium from calcium hydroxide and calcium silicate hydrate to form calcite (CaCO₃). From Figure 11, it can be understood that the increase in carbonation depth was proportional to the age of the concrete. The carbonation depth value of mixtures FS 40% and FS 50% were 5.45 mm and 8.41 mm, respectively, at the age of 365 days, which was closer to the cover of reinforcing steel bars and may cause corrosion. From the above observation, it was concluded that concrete with a substitution rate of up to 30% can be considered as a good concrete, since the carbonation coefficient was never exceeded the value of 6 mm/month^0.5 [36] (see Table 5). However, concrete with a substitution rate beyond 30% is not advisable for structural concrete, since the carbonation depth value of mixtures was closer to the cover of reinforcing steel bars.

3.3.4. Electrical Resistivity Test

The electrical resistivity test is one of the methods used to evaluate the durability properties of the concrete, and the resistivity provided by the concrete is directly proportional to the density and pore structures of the concrete. The electrical resistivity provided by all concrete mixtures was measured at the ages of 180 and 365 days and are presented in Figure 12. Limeira et al. and Chao-Lung et al. [11, 37] suggested that the minimum electrical resistivity value beyond which corrosion that cannot occur is 20 kΩ-cm. The obtained results revealed that the resistivity value of the concrete mixtures with a substitution rate of up to 30% were beyond 20 kΩ-cm in all ages, while the resistivity value of the concrete mixtures decreased with the increase in the FS rate, as shown in Figure 12. The CM showed an electrical resistivity by only 10.37% and 14.62% higher when compared to the FS 20% and FS 30% mixtures, respectively, at the age of 180 days. As discussed above, this is a result of the fact that the poor workability of the concrete due to the fineness of the FS. The poor workability of the concrete decreases the effective compaction of the concrete, leading to continuous pore structures. It is concluded that the effect of FS with the substitution rate of up to 30% has superficial effects on the resistivity properties, but the influence was profound beyond the substitution rate of 30%.

3.3.5. Sulphate Resistance

The sulphate resistance of the concrete was tested at the age of 180 and 365 days, and the results are presented in Figure 13. The test results revealed that the presence of FS decreases the sulphate resistance of the concrete, and this effect was further increased when the substitution rate was increased. At the ages of 180 and 365 days, the CM showed 6.18% and 13.41% decrease in compressive strength, respectively, due to sulphate attack. However, the mixtures containing FS showed a high reduction in compressive strength, and the effects were significant beyond the substitution rate of 30%. The decrease in sulphate resistance FS concrete is due to the presence of traces of sulphur in the FS. The presence of SO₃ may increase the strength of the NaSO₄ and MgSO₄ solution and enhances the ettringite formation (Ca₆(Al(OH)₆)₂(SO₄)₃(H₂O)_25.7), causing the deterioration of concrete. From the above observation, it can be concluded that the presence of reactive material in FS affects the durability properties of the concrete.

4. Conclusion

The reuse of FS as a substitute for natural sand in concrete production was evaluated based on the mechanical and durability properties of the resulting concrete. Based on the extensive tests carried out on the six mixtures, the following conclusion has been made.(i)The chemical analysis of FS indicated that FS can be a very suitable material for concrete production. However, the fineness and high water absorption of FS increases the water demand of the concrete by water absorption, decreasing the workability of the concrete, although the effect was profound beyond the substitution rate of 30%.(ii)In all ages of concrete, the mechanical properties of concrete mixtures containing FS up to 30% was relatively equal to the strength value of the CM. Compared to the mixture with FS 30%, the CM had showed its mechanical properties by 6.3% higher on average.(iii)The chloride penetration value of the CM was 420 coulombs, whereas the mixture FS 30% achieved the value of 621 coulombs at the age of 180 days, which is much less than the maximum value recommended in ASTM C1202-97.(iv)Since the carbonation coefficient of the concrete mixture with a substitution rate of up to 30% was never exceeded the value of 6 mm/month^0.5, it can be considered as a good concrete.(v)The CM increased electrical resistivity by only 10.37% and 14.62%, respectively, when compared to the FS 20% and FS 30% mixtures, at the age of 180 days.(vi)The presence of sulphur traces in the FS increased the strength of the NaSO₄ and MgSO₄ solution and enhanced the ettringite formation, causing the deterioration of concrete.(vii)It is recommended that the FS with a substitution rate up to 30% is favorable for the concrete production without adversely affecting the strength and durability criteria.
