ABSTRACT
The evaluation of the partial replacement of fine aggregate using rice husk in concrete is a significant area of research aimed at improving the sustainability and durability of concrete structures. This study investigates the potential of rice husk as a viable alternative to conventional fine aggregate in concrete mixtures. The experimental program involves the determination of the mechanical, physical, and durability properties of concrete containing varying percentages of rice husk as a partial replacement for fine aggregate. The rice husk is processed to obtain a suitable particle size distribution to ensure compatibility with the cement matrix. The mechanical properties of the concrete, such as compressive strength, tensile strength, and flexural strength, are evaluated at different curing ages. The physical properties, including workability and density, are examined to assess the influence of rice husk on the fresh and hardened state of the concrete.
