优选了 2种水下抗分散剂 ,即聚丙烯类的PVAD与纤维素类的HPMC ,并研究单掺与复掺配制技术对混凝土新拌性能、流动性、自密实度及对采用导管法成型的水下抗分散混凝土抗分散性与强度性能的影响 .研究结果表明 ,复掺配制的水下混凝土比单掺具有更好的水下抗分散性与强度性能
Two kinds of underwater anti-dispersant, namely PVAD and cellulose HPMC, were optimized. The effects of single-blending and compounding technology on fresh-mixability, fluidity and self-compacting of concrete, Of the underwater anti-dispersed concrete anti-dispersive and the strength of the performance of the results show that the composite concrete submerged concrete prepared with better than the single anti-dispersive and strength properties
