摘　　要：介绍了一种评价高效减水剂与水泥相容性的方法,使用该方法对10种高效减水剂与4种水泥之间的相容性进行了交叉试验,旨在考察某种高效减水剂对多种水泥和某种水泥对多种高效减水剂的相容性,以及在高效减水剂与水泥相容性之间何者的特性起主导作用。结果显示,对于同时在商品混凝土搅拌站采取的高效减水剂和水泥样品,高效减水剂对相容性的作用更大,同时证实市场上高效减水剂存在很大的质量差异,部分高效减水剂存在较大提高质量的空间。一些试验结果没有支持已有研究工作对高效减水剂与水泥相容性的某些观点。A review method for compatibility of superplasticizer and cement is introduced. The cross tests were made between 10 kinds of superplasticizer and 4 kinds of cement. Besides testing the compatibility, the leading place of two materials was tested out. The result shows in two specimens getting from ready-mixed concrete station at the same time, superplasticizer influenced more on the compatibility. Meanwhile, on market, superplasticizers quality differentials were exposed, and some of them can be improved through high-tech. On the other hand, the tests show some different results different from exresearch.
