The effects of laterite type on compressive and flexural strengths of concrete utilizing laterite-sand fine aggregate

This literature review examines the effects of laterite type on the compressive and flexural strengths of concrete when utilizing laterite-sand fine aggregate. The review provides a comprehensive overview of the research conducted in this area, highlighting the importance of understanding the properties of laterite and their influence on concrete performance. The main findings indicate that the type of laterite used as a fine aggregate significantly affects concrete strength. Factors such as gradation, mineralogy, moisture content, and reactivity of laterite impact the bonding with cement, workability, and overall durability of the concrete. The review emphasizes the need for standardized testing methods, optimization of mix proportions, long-term durability assessment, and considerations of sustainability factors in future research. The insights gained from the reviewed studies provide a foundation for subsequent experimental research and mathematical modeling, enabling the development of optimized mix designs and predictive models for utilizing laterite-sand fine aggregate in concrete construction.
