有机外加剂对硫铝酸盐水泥性能的影响

Effect of organic admixtures on performance of sulphoaluminate cement

本文就硅酸盐水泥常用有机外加剂对不同厂家所产硫铝酸盐水泥的性能影响进行了试验研究。结果表明,有机外加剂能够降低硫铝酸盐水泥的需水性,对硫铝酸盐水泥具有缓凝作用,但无益于硫铝酸盐水泥的强度发展。

In this paper, the effects of organic admixtures of portland cement on the pertormance ot sulphoalummate cement proauceu by different manufacturers were studied. The results show that the organic admixture can reduce the water requirement of sulphoalu- minate cement and has retarding effect on sulphoaluminate cement, but it is not conducive to the strength of sulphoaluminate cement.
