として重量割合を計算する。In the binder, the cement may be any of Portland cement, blast furnace cement, silica cement and fly ash cement defined in JIS. When using Portland cement, early-strength cement is desirable from the viewpoint of increasing the mold rotation rate. When the mixed cement is used, the weight ratio of the blast furnace quenched slag fine powder and the pozzolan fine powder such as fly ash mixed therein is calculated not as the cement but as the pozzolan fine powder.
