520			_aOne of the primary contributors to CO₂ emissions is the rapid increase in cement production within the construction industry and resource consumption across industrial sectors. Environmentalists have spent years urging researchers and builders to develop sustainable solutions to these problems. This research seeks to offer sustainable approaches to improper waste disposal by identifying waste materials that can be effectively utilized as binders or aggregates in mortar or concrete mixtures. This research thesis aims to evaluate the feasibility and potential benefits, both environmentally and economically, of producing concrete or mortar for the construction industry using industrial by-products, such as coal bottom ash and limestone powder considered in this research. The viability of replacing cement with coal bottom ash and limestone powder in mortar mixtures was tested through laboratory experiments, examining various replacement levels of 0%, 5%, 10%, 15%, and 20% by mass. This comprehensive analysis assessed how different replacement levels influenced the fresh and hardened properties as well as the cost-effectiveness and environmental benefits of using these wastes as alternatives to cement in mortar mixtures. The result of the analysis indicates that both wastes can be succesfully utilized as supplementary cementious materials at an Optimum level of 10% for Limestone powder and 15% for Coal bottom ash. This study concluded that both wastes can be an Ideal alternative to cement due to their pozzolanic capability and their significant influence on the properties of cement mortars. The study recommends further exploration of both wastes as sustainable alternatives to reduce green-house emissions, promote waste management and conserve natural resources.
