Application of Utility Function for Optimization and Ranking of Concrete Mix Designs

Calcium aluminate cement is considered a special cement due to its unique structure and the presence of at least ۴۰% aluminum oxide. It is highly durable under severe environmental conditions. However, challenges such as high cost and more importantly, sudden reduction in strength have limited its use as a standalone cement without structural modifications through alternative materials. The wide variety of these materials and their diverse effects on the various properties of this cement increase the number of variables, often causing confusion among engineers when selecting materials in different proportions. In this study, ۲۰ mix designs were prepared with replacement percentages of ۴۰%, ۲۵%, ۱۵%, ۵%, and ۶۰% of alternative materials including zeolite, slag, pumice, and limestone powder, and compared with a control mix. Subsequently, using the utility function, a concept from mathematics, the mixes were ranked from technical and economic perspectives.
