Table 4

Physical properties of mineral powder.

Property	Hydrophilic coefficient	Apparent density (g/cm^3)	Gradation
			Sieve size (mm)	Passing (%)	Technical criterion^a (%)
Value	0.77	2.742	0.6	100	100
			0.15	94.4	90~100
			0.075	80.3	75~100

^aThe technical criterion was based on standard JTG F 40-2004 [19].
