Study on the Proportion of Conglomerate Similar Materials Based on the Orthogonal Test

Table 1

Orthogonal design levels of quasi-conglomerate similar material.

Test level	Cement-to-water ratio	Cement-to-sand ratio	Quartz grain size (mm)
1	0.30	2	0.25 ∼ 0.50
2	0.35	3	0.50 ∼ 1.00
3	0.40	4	1.00 ∼ 2.00
4	0.45	5	2.00 ∼ 4.00
