| 摘要: |
| 优选了２种水下抗分散剂，即聚内类的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。 |

| Abstract: |
| In this paper, the effects of two optimal underwater antiwashout admixtures which were polypropylenetype PVAD and cellulosetype HPMC on the fresh concrete properties, fluidity and selfcompacting degree of concrete made with the technique of single addition and mixed addition respectively were studied. And the effects of the addition of them on the antiwashout resistance and strength of underwater concrete which was cast by tremie method were studied. The results indicate that the antiwashout resistane and strength of underwater concrete prepared with the technique of mixed addition is better than those of underwater concrete with the technique of single addition. |
