摘　　要：研究了水胶比、减水剂掺量、纤维素类絮凝剂掺量对水下不分散泡沫混凝土抗分散性能的影响。试验结果表明,当水胶比为0.48、羧甲基纤维素絮凝剂和减水剂掺量分别为0.08%和0.4%时,所制备的水下不分散泡沫混凝土的流动性和抗分散性的综合性能最佳。The effect of water to binder ratio, Polycarboxylate Superplaticizer and Carboxymethyl Cellulose on dispersion resistance of non-dispersible underwater foam concrete was studied. The results show that the comprehensive performance of fluidity and dispersion resistance is the best when there are 0.48W/B, 0.08% Carboxymethyl Cellulose and 0.4% Polycarboxylate Superplasticizer in the non-dispersible underwater foam concrete.
