SP－Ⅱ混凝土减水剂

SP-Ⅱ Water Reducing Agent for Concrete

介绍了ＳＰ－Ⅱ型混凝土：减水剂的合成方法，探讨了物料配比对产物性能的影响，结果表明，ＳＰ－Ⅱ混凝土减水剂加量小（一般为０．１％～０．５％），减水效果好，合成工艺简单，成本低，具有较好推广应用价值。

Synthesis of SP-Ⅱ Water Re(lucing Agent for concrete is described and effect of material mixdesjgn on product performance. Results show that only smal-addtiion of SP-Ⅱ water reducing agent for conerete (generally 0. 1 % to 0. 5 % ) is needed with good water reducing effect. Its synthetic technology is simple, cost low and of better value for popularization.
