| 摘 要： | 本文初步探索了使用特细砂,同时掺加高效减水剂、粉煤灰、硅灰等配制出C50￣C80的高强度混凝土的一系列性能,诸如和易性、强度、弹性模量等。试验结果表明采用低砂率,同时双掺高效减水剂和矿物掺合料时,在不增加水泥用量的前提下,完全可以配制出满足要求的C50￣C80的高强度混凝土。

| Abstract: | A series of performance such as workability, strength and elastic modulus of high strength concrete mixed with superfine sand, superplasticizer together with fly ash or silica fume was exploited. The results showed that the high strength concrete of C50~C80 can be made directly with low sand percentage, superplasticizer and mineral admixture, and without the addition of cement. |
