摘要
石灰石粉作为辅助胶凝材料以其经济环保而备受重视。为了说明石灰石粉掺量对砂浆28 d力学性能影响,通过石灰石粉替代水泥比分别为0,10%,20%,30%,40%,50%,60%,并应用灰色理论建立GM(1,1)模型,来定量分析石灰石粉掺量对砂浆抗压强度的影响。
As one kind of supplementary cementing materials, limestone powder has been paid more attention for its economic and environmental nature. This paper mainly gives a qualitative explanation to the effect of various amounts of limestone powder on mechanical properties of mortars at 28d age. The respective replacements of cement by limestone powder being 0, 10%, 20%, 30%, 40%, 50%, 60%, the influence of various amounts of limestone powder on compressive strength of mortar was analyzed quantitatively by using GM (1, 1) model.
