矿物掺合料对粉煤灰陶粒混凝土抗压强度的影响

Effect of mineral admixtures on compressive strength of lytag concrete

利用磨细粉煤灰、磨细矿渣和硅灰作为矿物掺合料,研究了各种矿物掺合料对粉煤灰陶粒混凝土抗压强度的影响。结果表明:单掺矿物掺合料的粉煤灰陶粒混凝土的28d抗压强度顺序是:硅灰>矿渣>粉煤灰;复掺矿物掺合料的粉煤灰陶粒混凝土的28d抗压强度顺序是:硅灰+矿渣>硅灰+粉煤灰>矿渣+粉煤灰。在此基础上,着重分析了各种矿物掺合料对粉煤灰陶粒混凝土抗压强度的影响机理和粉煤灰陶粒混凝土棱柱体抗压强度和立方体抗压强度的关系。

This paper studys the influence of the mineral admixtures such as ultra-fine fly ash,ultra-fine slag and silica fume on compressive strength of lytag concrete.And the results indicate that the rank of effect of the mineral admixture on the 28 d compression strength of lytag concrete is silica fumeslagfly ash.And when two mineral admixtures are combined to add into lytag concrete,the rank of effect of the mineral admixture on the 28 d compression strength of lytag concrete is silica fume and slagsilica fume and fly ashslag and fly ash.Based on experiments,it is analyzed that the effect of mineral admixtures on compressive strength of lytag concrete,and the relationship of prsim compressive strength and cube compressive strength of lytag concrete.
