Table 5

Chemical compositions of cement original materials in certain sampling period [3].

Material type	Loss (%)	SiO2 (%)	Al2O3 (%)	Fe2O3 (%)	CaO (%)	MgO (%)
Carbide slag	24.65	1.02	1.29	0.00	69.26	0.00
Clay	5.83	69.56	16.42	3.35	0.00	0.00
Sulfuric acid residue	1.06	11.05	2.22	77.85	2.45	2.71
Cinder	0.00	56.39	22.77	10.18	1.13	2.16

Assuming the cost and bond power index for the cement material in Table 5 are 18.00 ¥/ton, 25.00 ¥/ton, 48.00 ¥/ton, 9.00 ¥/ton, 11.24 Kwh/ton, 12.50 Kwh/ton, 19.86 Kwh/ton, and 13.80 Kwh/ton, respectively.
