Abstract

This study envisaged the application of Bottom ash as a replacement of fine aggregate. In this study, bottom ash is thoroughly mixed with a PC-based High range superplasticizer ( HRSP) having solid content more than 60%, this sand is called as modified bottom ash (MBA are mixed at doses of 0%, 0.25%, 0.5%, 0.75%, and 1% by weight of bottom ash. This prepared bottom ash is referred to as modified bottom ash (MBA). MBA is substituted for fine aggregates in ordinary concrete in varying amounts from 0 to 50% by river sand and the concrete has been tested for Compressive strength, flexural strength, split tensile strength, and other durability characteristics it has been found that 10% MBA produce superior outcomes, the purpose of use was not achieved. Therefore, MBA has been increased up to 60% replacement with fine aggregates, the strength and durability properties achieved for concrete produced by 50% MBA with fine aggregate (sand) are compared to 100% fine aggregate (sand) concrete and has observed similar results due to addition of HRSP. In the end, it can be concluded that High Range Superplasticizer HRSP is quite efficient for replacing Bottom ash with fine particles.
