ABSTRACT
Due to the high demand for concrete in construction, there was a corresponding high demand for the materials that make up concrete. As a result, it has become crucial to explore substitute for some of these constituents to reduce cost and increase availability. This research focuses on assessing the viability of using pulverized ceramic tiles as a partial replacement for fine aggregate in concrete. The experiment involved replacing fine aggregate in eight different sets at varying percentages, 5%, 10%, 15%, 20%, 25%, 30%, 35%, in order to identify the most suitable and acceptable level of replacement that wouldn’t compromise the structural integrity of the concrete. The test results for M30 grade concrete indicated that there was no significant difference in terms of strength between concrete made with natural river sand and concrete made with replacements. However, the highest compressive strength was achieved when 10% of the fine aggregate was replaced with pulverized ceramic tiles. Specifically, the average compressive strength after 7days curing was 28.2N/mm2, after 14days it was 33.28N/mm2, and after 28days it reached 35.79N/mm2. Therefore, the average compressive strength after 28days for the 10% replacement was 32.4N/mm2. in comparison, the average compressive strength after 28days for 100% fine aggregate was 28.67N/mm2. The concrete compressive strength rises as the percentage of PCT added increases up to 20%, reaching 32.35 N/mm2. However, beyond this point, the strength begins to decline with additional PCT incorporation.
