大同冀东水泥混凝土坍落度损失较快问题的处理

On treatment of concrete fast slumps of Jidong cement in Datong

针对大同盾石混凝土有限公司的混凝土坍落度损失较快的问题进行了原因分析,从聚羧酸减水剂母料的最高掺量、保坍剂、硫碱比调整三个方面提出了坍落度损失较快的处理措施,并研究了外加剂掺量的问题,以降低混凝土成本。

The paper analyzes reasons for the concrete fast slump damages of Datong Dunshi Concrete Co.,Ltd,points out measures for the concrete fast slump damage from the maximal mixing volume of carboxylic acid water reducing agent masterbatch,concrete slump retaining agent,sulfur-alkali ratio adjustment,and researches the additive mixing volume,so as to lower the concrete cost.
