高效减水剂与水泥及掺混合材水泥的相容性研究

Study on the Compatibility of Superplasticizer with Straight cement and Admixture Cement

通过对掺高效减水剂水泥净浆流动性及流动性损失的测定试验,研究了高效减水剂与水泥及掺混合材水泥的相容性。试验结果表明,同一种高效减水剂与不同水泥的相容性不同;矿渣和粉煤灰都能改善水泥与高效减水剂的相容性;复掺粉煤灰和矿渣比矿渣单掺时改善效果好。

The compatibility of the superplasticizer with straight cement and admixture cement is investigated by testing the fluidity loss of cement pastes containing the superplasticizer added. The test results indicate that one kind of superplasticizer has different influences on different kinds of cement. The compatibility of the superplasticizer with cement can be improved when admixtures （i. e. fly ash, slag） are added; the combined use of fly ash and slag will improve the fluidity of cement paste much more than only slag is added.
