摘要
以水胶比、胶凝材料总量等因素为变量,设计了五因素四水平的L16(45)正交试验,测定了标准养护试件的28 d和56 d的混凝土碳化深度,并通过极差和方差分析,得出了各因素的影响程度排序,并找出最佳配合比,为高性能混凝土配合比设计提供了实验依据。
Taking water binder ratio,total cementing materials and other factors as variables,this paper designed the L 15（45） orthogonal test of five factors and four levels,measured the concrete carbonization depth of standard curing test pieces 28 d and 56 d,and through range and variance analysis,gained the influence degree ranking of each factor,and found out the best mix ratio,provides the experimental basis for the mix ratio design of high performance concrete.
