Abstract

It is well known that the water reducing rate of concrete are affected by the kind of organic admixtures. Organic admixture can improve the properties of concrete. Sulfonated Naphthalene - Formaldehyde(Pn) superplasticizer and Poly - carboxylate(Pc) are used representatively, but most study deal with alkali - activator and amorphous binder. In this study, we investigated the influence of mixture ratio of superplasticizer's type on the water reducing rate and compressive strength. In view of the results, we found that the admixture ratio of superplasticizer's type results to be significant factors. It is represent that water reducing rate of Pn and Li is about 16 % in the dosage of 2 %, but air content was severly increased in the case of Li. Also the compressive strength was increased with superplasticizer's ratio is until 0.5 %.
