        abstract = {In the last decade, the use of supplementary cementitious materials (SCMs) has become an integral part of high-strength and high-performance concrete mix design. These materials may be natural resources, industrial by-products, or wastes, or materials that require comparatively less energy and time for production. Commonly used SCMs include fly ash, silica fume (SF), ground granulated blast furnace slag (GGBS), and rice husk ash (RHA).Rice husk ash is a by-product obtained from the controlled combustion of rice husk and mainly consists of non-crystalline silicon dioxide with a high specific surface area and excellent pozzolanic reactivity. Owing to these characteristics, RHA has been widely used as a pozzolanic material in mortar and concrete and has demonstrated a significant influence in enhancing both mechanical and durability properties. Although silica fume contributes to high strength development, its cost has increased considerably in recent years, making its large-scale use uneconomical for meeting the growing demands of the construction industry.In the present study, RHA is used as a partial replacement of cement in high-performance concrete (HPC) at different replacement levels. The effect of cement replacement with RHA on the mechanical properties of HPC is investigated. Concrete cube, cylinder, and beam specimens of various HPC grades, within the strength range of 60–100 MPa, are cast and tested to evaluate compressive strength, tensile strength, and flexural strength.},
