Experimental Study on Partial Replacement of Natural Coarse Aggregate with Marble Waste Aggregate in Concrete

Abstract

Abstract: Marble waste is produced from marble industries as a result of production. More production equals more waste, more waste creates environmental contamination. A high volume of marble production has generated a considerable amount of waste materials; almost 70% of the minerals gets wasted in the mining, processing and polishing stages which have a serious impact on the environment. Also, a large amount of marble is accumulating in the environment due to demolition of old structures having marble. This causes environmental pollution. An economically viable solution to this problem should include utilization of these waste materials for new products especially in construction applications which in turn minimizes the heavy burden on the nation’s landfills, saves natural resources, energy and reduces environmental pollution. Present study work is concerned with studying the feasibility of partial replacement of coarse aggregates with marble waste. Varying percentages of replacement is considered 0%, 10%, 20%, 30%, 40% and 50% by natural aggregate, From the results of current experimental study, it is concluded that Compressive strength of the concrete cubes at 7 and 28 days shows 29.87 and 41.89 N/mm2 till 40% marble waste coarse aggregate used as replacement of coarse aggregate in concrete. Hence the marble waste coarse aggregates can be used in concrete works up to as 40 % replacement.
