Optimum chemical composition and Blaine size of the cement for maximum concrete compressive strength based on a novel power formula

Globally, the annual consumption of concrete reaches 30 billion tonnes, which translates to a per capita usage that is threefold compared to four decades ago. The demand for concrete is increasing at a rate that surpasses that of steel and wood. This article aims to explore the influence of both chemical and physical factors on the compressive strength of concrete. The effects of these variables were determined through a fitted power equation correlating them with experimental data on concrete compressive strength. The resulting formula demonstrated a high degree of accuracy, exhibiting a mean absolute error of less than 3% when applied to experimental data from concrete specimens subjected to varying curing durations. The investigation into the impact of these factors was conducted by analyzing the power of each variable within the established equation. Additionally, an optimization algorithm was employed to identify the ideal cement composition and particle size that would yield the maximum compressive strength of concrete, with this optimal condition being validated through experimental methods.
