        abstract = {This study investigates the compressive strength behavior of solid concrete block masonry prisms assembled with varying mortar grades and block sources. While numerous experimental investigations have examined clay brick masonry, limited research exists on the performance of solid concrete block masonry, despite its increasing adoption in modern construction due to cost efficiency, availability of industrial by-products, and superior structural properties. To address this gap, an extensive experimental program was conducted using solid concrete blocks procured from three different sources combined with mortars of five distinct mix ratios. A total of 45 masonry prism specimens were prepared, cured for 28 days, and tested under axial loading conditions in accordance with IS standards. The experimental results demonstrated a strong dependency of prism compressive strength on both mortar grade and block strength. Statistical multiple regression analysis was applied to the dataset, resulting in a predictive mathematical model that achieved a high correlation (R² = 0.98) between experimental and predicted values. The proposed equations capture the influence of mortar and block compressive strengths, providing a reliable tool for estimating prism strength under varying construction conditions. Furthermore, a structural reliability analysis was performed using Monte Carlo simulation to evaluate the probability of failure and reliability index for prisms across different mortar grades. Results indicated that all tested configurations exhibited probabilities of failure within the acceptable 5% limit, confirming the applicability of the derived equations for design and assessment.The outcomes of this study contribute to the advancement of masonry design by offering both experimental evidence and analytical models for solid concrete block masonry. The findings provide a framework for reliability-based design approaches, supporting the wider application of solid concrete blocks in structural engineering practice.},
