Experimental investigation on utilization of silty sand, lime, gypsum to improve mechanical properties of fly ash

Abstract

Abstract Researchers globally due to little cost and effective results in engineering applications frequently use the waste material. Every year millions of ton of waste like Fly ash, lime, gypsum had generated from the kilns. In addition, mainly in this research focused on application of Silty Sand, Which have been produced on very large scale along the dam site, A huge amount of the this sand went for dumping to the nearby site. The dumping of Fly ash from industries near habitable areas poses environmental threats like air pollution, water contamination and affects biodiversity. This empirical investigation mainly focused on utilization of waste material like Silty sand, Lime and Gypsum to replace Fly ash in different mixes. In this research different mix have prepared by addition of Silty sand, Lime and gypsum to the voluminous weight of Fly ash, and silty sand have added in four different percentage of mixes to replace Fly ash by 10, 20, 30 and 40% by weight. Following tests have conducted standard proctor test and unconfined compressive strength test and final the result of test reveals that by addition of 10% of silty sand and the samples and cured by burlap method Unconfined compressive strength have highest i.e. 64.58 KPa with 56 days curing period.
