摘要
根据珍珠岩掺合料混凝土的试验研究数据,选取掺量、水灰比和养护龄期为混凝土抗压强度的自变量,采用SPSSV11软件的相关分析和非线性回归分析,得出混凝土抗压强度随珍珠岩粉替代水泥掺量、水灰比和养护龄期的方程式f=11 90·t0 16·EXP[-0 77·(a/b)]·(w/b)-1 06,并对该方程进行精度评估。
Based on experimental data about concrete mixed with perlite powder,using advanced multinomial statistics software SPSS V11,the article focuses changes on compressive strength with mixing content of perlite powder,ratio of water to binder and curing time.By means of nonlinear regression,the formulation is obtained as follow:f=11.90·t^(0.16)·EXP·(w/b)^(-1.06),it provides an excellent prediction of the compressive strength concrete.
