Aim: The intention of this study was to analyze the improvement of compressive strength in MSand concrete by adding 20% Alccofine compared to conventional concrete. Materials and Methods: In this study, M-Sand was used as the fine aggregate, cement and water were used as per standard concrete production procedures, and Alccofine was used as a pozzolanic material. The samples were made by adding 20% Alccofine by weight of cement to some of the concrete samples. The samples were then cast into cylindrical molds and cured under controlled conditions. The compressive strength of both specimens was measured after 28 days of curing using a compression testing apparatus. A sample size of 18 was determined for both the proposed M-Sand specimens and the conventional concrete specimens, based on a power analysis using a G-power of 0.8, α=0.05, β=0.2, and a 95% confidence interval.
