In this study an experimental investigation on production of self-compacting concrete with bagasse ash as partial replacement of fine aggregate is done. River sand has been partially replaced with bagasse ash from 0% to 80% by volume. Cement and fly ash is used as a powder material. Two concrete mixtures with cement content of 375 Kg/m3 and 500 Kg/m3 was proportioned. The workability properties such as slump flow, inverted flow, V-funnel flow time and J-ring flow were measured. The hardened properties such as density, compressive strength, split tensile strength, modulus of elasticity and flexural strength of concrete in each mixture were measured at various ages. Water absorption and weight loss ratio on drying of concrete was measured at 28 days. Micro structural properties such as SEM and XRD analysis were examined for SCC specimens.From the test results, it was found that (a) Workability properties depends upon the bagasse ash content (b) Partial replacement of BA up to 20% by volume of bagasse ash enhanced both the workability and hardened properties of self-compacting concrete (c) SEM micrograph images shows that irregular porous particles increases as BA increases and XRD pattern reveals that presence of silica peak increases as the BA content increases from 10% to 80%.
