Evaluate the influence of materials on rheology of self-compacting concrete mixtures using analysis of variance

Abstract

In this research, analysis of variance (ANOVA) was carried out using the software SPSS to evaluate the influence of each material component on the performance of the self-compacting concrete (SCC) with a significance level of 5%. When there is a difference, Dunnett's T3 or LSD tests are used to compare the average values of these material components. The experimental results indicate that all material components have an impact on the performance of self-compacting concrete mixtures, including workability, rheological properties, and pumpability, to varying degrees, in which, the change in the water-to-binder ratio has a significant influence on all parameters (Robust Tests with Sig. Welch <0,0001, Dunnett’s T3 with Sig. <0,0001).
