机制砂和聚羧酸减水剂在普通混凝土中的应用

Application of sand and polycarboxylate in ordinary concrete

结合生产实际,本文介绍了用机制砂代替河砂,聚羧酸减水剂代替脂肪类减水剂配制普通混凝土具体做法及实用效果。以及采用机制砂、聚羧酸减水剂所产生的经济和社会效益。

Combined with the actual production,this paper introduces the preparation and practice effect of ordinary concrete by using mechanism sand instead of river sand and polycarboxylate water reducer instead of the aliphatic supeiplasticizer. And introduces acid water reducing produced by the economic and social benefits of using mechanism of sand and poly carboxylic.
