Utilization of Ceramic Waste Powder and Bagasse Ash as Partial Replacement of Cement in Concrete

The construction sector consumes large quantities of cement, contributing significantly to global CO₂ emissions and environmental degradation. To address these issues, this study investigates the combined use of Ceramic Waste Powder (CWP) and Sugarcane Bagasse Ash (SCBA) as partial replacements for cement in M30 grade concrete. Experimental mixes were prepared with replacement levels of 0%, 10%, 20%, 30%, and 40%, and specimens were tested at 7, 14, and 28 days. Results indicate that 10–20% replacement levels enhance or maintain compressive strength comparable to conventional concrete, while higher replacement levels lead to reduced performance. The optimum replacement level was found to be 20%, providing improved sustainability without compromising strength. This study demonstrates that incorporating CWP and SCBA can significantly reduce cement consumption, lower carbon emissions, and promote environmentally conscious construction practices.
