Influence of Bottom Ash as Partial Replacement for Fine Aggregate on the Properties of Hybrid Fiber Reinforced Cement Concrete

Abstract

Abstract: The major problem the world is facing today is environmental pollution. In the construction industry mainly the production of Portland cement will cause the emission of CO2 which results in environmental pollution. On the other hand, the problem of depleting natural resources can be solved by the usage of industrial by-products obtained from the construction industry. concrete technology is heading towards an entirely new era by the use of Bottom ash, polypropylene fibers & Steel fibers in concrete. Concrete when mixed with fibers, give fibrous concrete. The mechanical property of fibrous concrete is superior to that of ordinary concrete. Bottom ash will be evaluated for use as supplementary Fine aggregate material in Fine aggregate based system, the performance of Bottom ash mixtures will be compared to controlled mixtures and mixtures incorporating Bottom ash as replacement for Fine aggregate.

 In this present study, the effect of bottom ash on strength parameters and durability properties of hybrid fiber reinforced concrete are assessed. Fine aggregate is replaced with bottom ash by 5%,10%,15%,20%,25% and 30% in concrete specimens with 1% of hybrid fibers. Hybrid fiber (0.5 % of steel fibers and 0.5 % polypropylene fibers) were taken by total volume of concrete. The experimental studies show that bottom ash can be used in concrete as partial replacement for the fine aggregate without any effect on strength and durability.
