To address this issue, this research focused on evaluating the strength of M20 grade concrete from five different Ordinary Portland Cement (OPC-43) brands available in Nepal: Brands A, B, C, D, and E. A series of comprehensive tests such as compressive strength tests, sieve analysis, Los Angeles Abrasion tests and Aggregate Impact Value test were carried out. The compressive strength tests revealed significant variations among the cement brands. For instance, at 7 days, the highest compressive strength observed was 28.08 N/mm² from Brand A, while the lowest was 13.10 N/mm² from Brand C. At 28 days, the highest strength recorded was 33.63 N/mm² from Brand D, and the lowest was 19.41 N/mm² from Brand C. These discrepancies highlight the need for better quality control and accurate labeling. By analyzing the performance of each cement brand, we aim to help contractors and project managers choose the best materials for building more durable reinforced concrete roads. Our findings suggest that reinforced concrete roads could be a more reliable and low-maintenance solution, especially suited for Nepal's challenging terrain and climate. We recommend further research to explore a wider range of cement brands and improve testing standards to ensure better road construction practices in Nepal.
