Statistical analysis of the effective factors on the 28 days compressive strength and setting time of the concrete

In this study, the effects of various factors (weight fraction of the SiO(2), Al(2)O(3), Fe(2)O(3), Na(2)O, K(2)O, CaO, MgO, Cl, SO(3), and the Blaine of the cement particles) on the concrete compressive strength and also initial setting time have been investigated. Compressive strength and setting...

description In this study, the effects of various factors (weight fraction of the SiO(2), Al(2)O(3), Fe(2)O(3), Na(2)O, K(2)O, CaO, MgO, Cl, SO(3), and the Blaine of the cement particles) on the concrete compressive strength and also initial setting time have been investigated. Compressive strength and setting time tests have been carried out based on DIN standards in this study. Interactions of these factors have been obtained by the use of analysis of variance and regression equations of these factors have been obtained to predict the concrete compressive strength and initial setting time. Also, simple and applicable formulas with less than 6% absolute mean error have been developed using the genetic algorithm to predict these parameters. Finally, the effect of each factor has been investigated when other factors are in their low or high level.
