摘　　要：本文用国产水溶性聚合物,通过对水下不离散砼的抗离散性、流动性、强度和电化学性能等进行了研究,同时利用高倍偏光显微镜、扫描电镜观察了砼的微观结构,分析了聚合物与砼的相互作用及其赋予砼水中不离散的机理。In this paper, some properties such as segregation resistance, flow, strength and |ζ|electric potertial of undispersed underwater concrete containing water-soluble polymers was studied. Microstructure was abserved by means of micropolariscope and SEM. The mechanism for the effect of polymers in undispersed underwater concrete was investigated.
