商品混凝土 2010年第10期 Beton Chinese Edition ——Ready-mixed Concrete 研究探索 脂肪族和聚羧酸高效减水剂与水泥相容性的试验研究 逄鲁峰，蔡永涛 （山东建筑大学 土木工程学院，山东 济南 250101） [ 摘要 ] 为了研究高效减水剂与水泥之间的相容性，本文进行了一系列净浆试验。研究结果表明 ：不同类型的减水剂与不同水泥所 表现出的相容性差别很大，不同品牌的聚羧酸减水剂与不同水泥的相容性也有较大差别。并通过液相色谱予以初步分析。最后对 脂肪族和聚羧酸进行不同比例复合试验，结果表明 ：复配聚羧酸和脂肪族可以改善其与水泥的相容性，同时降低成本。 [ 关键词 ] 相容性 ；效果比例 ；聚羧酸 ；脂肪族 ；复配 》 Experimental research on compatibility between two superplasticizers and cement 土 Pang Lufeng, Cai Yongtao (Department of Civil Engineering, Shandong Janzhu University, Jinan 250101, Shandong) Abstract: In order to study the compatibility between superplasticizers and cement, a series of cement paste were tested. Results 凝 showed that: There were large difference for the compatibility between different superplasticizers and different cement . Difference also exist in the compatibility between different brands of Polycarboxylate and different cement. Liquid chromatography was used for analyzing the reasons. Finally, the test which mixed the Polycarboxylate and Aliphatic water reducer in different ratio was investigated. The results indicated that: mixing the two superplasticizers above can improve its compatibility with cement, while reducing costs. 混 Key word: compatibility; effect ratio;polycarboxylate;aliphatic;composite;preparation 0 前言 品 保坍性能一般，但其减水率相对于萘系要稍高一点，并且具有 早强的特性，具有一定的市场份额。新一代高性能聚羧酸减水 随着混凝土技术的迅速发展，混凝土组分逐渐趋于多样 剂因其相对很低
