Geotechnical Engineering Properties of Soils Solidified by Microbially Induced CaCO₃ Precipitation (MICP)

Table 4

Effect of soil particle size on consolidation.

Material	Particle size	Conclusion	Reference
Sand	A: 1.25∼2.5 mm	Group C has the highest unconfined compression; the intergranular pores are easily filled by CaCO3 crystals	[73]
	B: 0.5∼1.25 mm
	C: 0.04∼0.5 mm
Sand	Mikawa D50 = 600 μm	The UCS of Mikawa sand is higher than that of Toyoura sand	[74]
	Toyoura D50 = 200 μm
Sand	Ottawa silica D50 = 0.46 mm	The solidification strength of Ottawa silica sand is higher than that of Mississippi sand	[42]
	Mississippi D50 = 0.33 mm
