摘要
复掺粉煤灰和硅灰应用到自密实混凝土中,可以增大新拌混凝土的流动性,改善离析泌水,增加混凝土硬化后的强度,提高其耐久性能。试验研究了粉煤灰的最佳掺量,以及几种矿物质掺合料复掺的复合效应。
Fly ash compounding with silica fume used in self-compacting concrete can not only improve the flowability of fresh concrete,but also better segregation and bleeding,improve the strength and durability of hardened concrete.The optimum amount of fly ash and the compounding effect of several mineral admixture are expounded through experimental investigation.
