摘要
讨论了两种减水剂对于矿渣微粉的的适用性问题。通过对比试验分析,研究表明FDN减水剂和木质素磺酸钙减水剂对矿渣微粉的胶结特性有一定的影响,可改善拌合物流变性能;在相同和易性时可以降低水灰比,提高强度;减水剂的效果与减水剂的种类及性能有关。
This article discusses the serviceability of two kinds of superplascizers to slag powder. The results of test show that FDN water-reducer and calcium lignosulfonate superplasticizer can improve theological properties. When workability is same, water-cement ratio can be reduced and strength can be improved at same time. The effect of water-reducing is related to superplasticizer＇s type and performance
