This work studies the effect of curing time in mold on the strength and other properties of lowcement corundum castables, exploring the feasibility of reducing the curing time in mold.
The results show that AS cement possesses high early strength, low hydration heat and durability, but its shrinkage rate is higher than that of portland cement.
结果表明,碱-矿渣水泥具有早强、高强、低水化热和高耐久性等优良性能,但是干缩较大;

In view of the high cost and lowstrength of the paste cement filling used at present in mines, it was proposed to use partial fly ash in stead of cement as the binding agent.
