PERFORMANCE OF CERAMIC WASTE AS PARTIAL REPLACEMENT OF COARSE AGGREGATE IN CONCRETE
Due to the extensive use of concrete in Ethiopia during the last few decades, the demand for concrete materials has risen quickly. Due to a lack of supplies, the Ethiopian construction industry is now looking for substitute ingredients for concrete. While there is a significant need for coarse aggregate, aggregate production is having a negative impact on the environment. The purpose of this study is to see how well ceramic tile waste performs as a partial replacement for coarse aggregate in C-25, and C-30 concrete grades. The workability, unit weight, durability, and strength characteristics experiments were carried out on selected concrete grades through ceramic tile waste replaced by coarse aggregate at proportions of 10%, 20%, 30%, and 40%, and the obtained results were compared to conventional concrete. The study found that replacing 20% of ceramic tile waste as an alternative of coarse aggregate reduced the unit weight of concrete and pointedly increases the compressive and tensile strength of concrete, and additionally it absorbs less water than conventional concrete. Henceforward using of Ceramic Tile waste in the concrete construction activities offers technical and environmental benefits, as well as resulting in lightweight concrete construction.
