摘要
本文介绍了如何用525普通硅酸盐水泥及高效减水剂配制 C_(50)混凝土的经验,经长春香格里拉大酒店工程实践.证明了与原混凝土施工配合比相比,每立方米混凝土成本可降低30元左右.用高效减水剂代替早强剂,每立方米混凝土可节省8元左右.为正确使用高效减水剂提供了新的思路.
This article interprets how to compound C_(50)high-strength concrete with 525 ordinary portland cement and high-effective water reducing admixture.This method has been applied to the project of Changchun Shangri-la Hotel.Comparing with the original construction mixed proportions,the cost of concrete per cabic metre was testified to be decreased to 30 R.M.B.Yuan.Instead of concrete early strength admixture with the high-effective water-reducing admixture,the cost of concrete per cabic metre was de- creased to 8～10 R.M.B.Yuan.It provides a new way to use high-effective water-re- ducing admixture.
