The review highlights the effects of varying water-cement ratios on compressive and tensile strength in concrete mixes, suggesting optimal ratios for construction.
The water-cement ratio (w/c) is one of the most critical parameters governing concrete strength and durability. This comprehensive review examines the influence of varying water-cement ratios on concrete compressive, tensile, and flexural strength characteristics. The study synthesizes research findings from multiple investigations conducted prior to 2020, analyzing the relationship between w/c ratios ranging from 0.25 to 0.70 and their corresponding effects on mechanical properties. The review incorporates data from various concrete mix designs, curing conditions, and testing methodologies to provide a comprehensive understanding of w/c ratio impacts. Results consistently demonstrate an inverse relationship between water-cement ratio and concrete strength, with optimal ratios typically ranging between 0.35 and 0.45 for most structural applications. The paper provides quantitative analysis through comparative tables and graphical representations, establishing guidelines for mix design optimization in construction practice.
