EXPERIMENTAL AND STATISTICAL ANALYSIS OF AGGREGATES REPLACEMENT BY DIFFERENT CERAMIC WASTE
Main Article Content
Abstract
This study investigates the utilization of ceramic waste as a partial and complete replacement for natural aggregates (fine and coarse) in concrete, aiming to enhance its mechanical features and promote sustainability in construction. Ceramic waste was incorporated at substitution ratios of 0, 25, 50, 75, and 100%, and its impact on compressive, tensile, and flexural strengths was evaluated at 7 and 28 days. Experimental findings demonstrated that fine aggregate substitution with ceramic waste achieved optimal mechanical performance at 75%, with significant improvements in strength features due to enhanced interfacial bonding and particle packing. Conversely, coarse aggregate substitution showed diminishing strength beyond 25%, indicating limited compatibility at higher levels. Statistical analysis using one-way ANOVA confirmed the significant influence of ceramic waste on concrete performance, with P-values below 0.05 for all tested features. The findings highlight ceramic waste's potential as a sustainable material for reducing dependency on natural aggregates while addressing waste management challenges. This research underscores the dual benefits of improved mechanical performance and environmental sustainability, providing a practical framework for integrating ceramic waste into eco-efficient concrete production. Future studies are recommended to explore long-term durability and lifecycle assessments to reinforce its viability in structural applications.
