摘要
文中对不同粉煤灰掺量(10%、20%、30%)及不同矿渣掺量(15%、30%,矿渣与粉煤灰的比例)下水工混凝土力学强度的变化规律进行了研究.结果表明,养护时间越长,混凝土力学强度-粉煤灰掺量演变曲线的斜率更大;随着养护龄期的增加,混凝土抗压及抗拉强度-矿渣掺量演变曲线的斜率更大;当粉煤灰掺量为20%及矿渣掺量为15%时,混凝土的抗压和抗拉强度均达到最优.
Abstract
In this paper,the variation of mechanical strength of hydraulic concrete under different fly ash content(10%,20%,30%)and dif-ferent slag content(15%,30%,the proportion of slag to fly ash)was studied.The results show that the slope of the evolution curve of con-crete mechanical strength-fly ash content is larger with the longer curing time.With the increase of curing age,the slope of the evolution curve of concrete compressive and tensile strength-slag content is larger.When the fly ash content is 20%and the slag content is 15%,the com-pressive strength and tensile strength of concrete are the best.
