摘要
通过磨细水渣掺入混凝土的试验 ,表明水渣延缓了水泥的水化速度 ,降低初期的水化热 ;降低坍落度损失 ,有效地改善了泵送混凝土的工作性。
? According to the experiment of adding grinded hydrated scoria into pumping concrete,we find that it is grinded hydrated scoria that decreases the hydrating speed,the initial hydrating heat of cement and slumping loss of pumping concrete and improves the workability,strength and durability of pumping concrete. 〔
