DETERMINATION OF THE COMPRESSIVE STRENGTH OF CONCRETE WITH HIGH VOLUME CONTENT OF RICE HUSK-ASH (HVCRHA)

ABSTRACT The quest for sustainable construction materials has led to innovative solutions aimed at reducing the environmental impact of the construction industry. One such endeavor is the incorporation of alternative and locally sourced materials into concrete production, among which rice husk ash (RHA) has gained prominence. This study focuses on the "Determination of the Compressive Strength of Concrete with High Volume Content of Rice Husk Ash," as it investigates the potential of RHA as a supplementary cementitious material. Concrete, a fundamental construction material, traditionally relies heavily on Portland cement, a resource-intensive and carbon-emission-intensive material. In contrast, RHA, an agricultural waste byproduct, can be transformed into a pozzolanic material with the potential to enhance concrete properties while reducing the environmental footprint. The research involved the production of concrete mixtures with varying percentages of RHA as a partial replacement for cement. A series of laboratory tests, including the determination of compressive strength, were conducted to assess the mechanical properties of the concrete. The "Determination of the Compressive Strength of Concrete with High Volume Content of Rice Husk Ash" contributes to the growing body of knowledge on sustainable construction materials and techniques. The results have practical implications for the construction industry, as they provide a basis for the utilization of RHA in concrete mix design. This research supports the transition toward environmentally responsible and economically viable construction practices, a fundamental step toward a more sustainable and resilient built environment.
