Abstract
AbstractThe Design of Experiment (DOE) is a widely recognized approach to designing and analyzing experiments. It is a statistical method utilized to simultaneously examine the impact of multiple factors on the results. In this study, two different DOE methods, including mixture and factorial design were employed to evaluate the influence of various factors on the performance of ternary binders. To assess the effect of each component such as Portland cement (PC), calcium aluminate cement (CAC) and sulphate (CŜHx) on the workability and strength of ternary binders, mixture design was utilized. A two‐stage factorial design was implemented to investigate the impact of various factors on the fresh and hard properties of ternary binders. In the first stage the influence of composition, supplementary cementitious material (SCM) and cement replacement ratio were examined. In the second stage the impact of composition, CAC and CŜHx type were analyzed. Principal Component Analysis was also employed to analyse the continuous data obtained from the XRD patterns. The study results indicated that increased CAC and CŜHx content in the mixture enhances the workability of the pastes. High compressive strengths were found to be a result of increased cement content in the mixture and low SCM substitution.
