摘要

The construction industry pollutes the environment and consumes the natural resources. Aiding sustainability can decrease the impact caused by the construction industry. This study investigates the potential of utilizing waste materials as supplementary cementitious materials (SCMs) for partial cement replacement. Limestone Powder (LP) and Ceramic Waste Powder (CWP) are examined for suitability in concrete and mortar studies. The research aims to review the influence of these SCMs on workability, setting time, strength development, and durability of the concrete using these materials. Material characterization using X-ray diffraction (XRD) and scanning electron microscopy (SEM) were studied to analyze chemical compositions. Physical characterization are studied for these waste materials. Workability, setting time (initial and final setting time), and mechanical properties (compressive and flexural strength) were assessed. Earlier studies have observed using different forms of CWP and LP as aggregates and supplementary cementitious materials (SCMs) in concrete and mortar mixtures. This exploration contributes to developing sustainable construction materials by promoting waste products as alternatives for Ordinary Portland Cement as eco-friendly cementitious materials.
