试验研究表明,粉煤灰混凝土的强度、抗碳化等指标与所取配合比有关,在合宜的配合比条件下,其抗压强度可以满足现行规范28天抗压强度的要求,而其抗碳化性能甚至优于普通混凝土。从150号粉煤灰混凝土孔结构试验结果看,普通混凝土结构中大多为孔隙半径等于986.4A°的大孔,等量取代法的粉煤灰混凝 Experimental studies have shown that the strength, anti-carbonation and other indicators of fly ash concrete are related to the mix ratio adopted. Under the appropriate mix ratio, the compressive strength can meet the requirements of the current specification for 28 days compressive strength, and its anti-carbonation The performance is even better than ordinary concrete. From the test results of the No. 150 fly ash concrete pore structure, most of the ordinary concrete structures are large pores with a pore radius equal to 986.4 A° and fly ash coagulation with equivalent replacement method.
