Assessment of the Effect of Replacing Normal Aggregate by Porcelinite on the Behaviour of Layered Steel Fibrous Self-Compacting Reinforced Concrete Slabs under Uniform Load

Table 9

Effect of replacing normal-weight aggregate by lightweight aggregate on the splitting-tensile strength, compressive strength, and density with various (V_f) values.

Concrete type	Vf (%)	ft (MPa)	Percentage of decrease	fcu (MPa)	Percentage of decrease	Density (kg/m^3)	Percentage of decrease
Normal weight	0	3.2	—	30.5	—	2336	—
Light weight	0	2.4	25	19	37.7	2008	14
Normal weight	0.4	4.3	—	35.5	—	2377	—
Light weight	0.4	3.0	30.2	21.3	40	2045	13.9
Normal weight	0.8	5.3	—	38.1	—	2405	—
Light weight	0.8	3.7	30.18	23.5	38.3	2080	13.5
