ABSTRACT
A high amount of tile production is occurring in India as well as other countries due to its high demand and versatile use for various aesthetic appearances. This high demand also contributes to the increase in wastage of tiles, but today the only option available for the disposal of ceramic waste is landfill. This research intends to recycle these tile wastes efficiently as a partial replacement of nominal coarse aggregates with tiles aggregates. Concrete formed by using crushed tiles as coarse aggregate is tested for its scope in constructing pavement blocks using this concrete. Experimental studies were carried out to find the comparative compressive strength of concrete (M30) by making nominal concrete cubes at various mix percentages and testing at a maturity period of 28 days. An empirical regression-based model was also formulated for the evaluation of the mechanical strength of concrete at varying ceramic waste coarse aggregate (CWCA) percentages. Cost comparison based on the cost of raw materials and carbon taxes in various countries was also made in this study.
