Abstract

This study investigates the compressive strength of concrete using hybrid cement as a binding material, which offers the advantages of lower energy consumption and reduced carbon dioxide emissions during production. The study examines concrete mixtures using Portland and hybrid cement under varying curing times. The primary objective is to develop a predictive model for concrete compressive strength using multiple linear regression analysis and to identify factors influencing compressive strength by comparing the predicted results with laboratory test data. The findings reveal that concrete using hybrid cement shows compressive strength trends similar to Portland cement concrete. Hybrid cement concrete exhibits higher compressive strength with increased curing time than Portland cement concrete. Furthermore, statistical analysis indicates that the predictive model can accurately forecast compressive strength with 92.00% accuracy, with curing duration and water-to-cement ratio identified as the most significant factors. This study provides a valuable reference for developing sustainable concrete and has applications in building construction and infrastructure development.
