Influence of Foundry Sand C and D Waste in Fibre Reinforced High Strength Concrete

Abstract

In this investigation, the effect of addition of waste foundry sand as partial replacement of 0%, 10%, 20%, 30% and 40% by adding with and without poly propylene fibers to the regular sand in concrete and also construction and demolitions as partially replacement of 0%, 5%, 10%, 15% and 20% by adding poly propylene fibers as per IRC44-2017 guidelines for M50 grade of Concrete. The aim of this study is to evaluate the optimum percentage replacement of both foundry sand and C and D waste combindly in the same M50 grade concrete mix to determine compressive strength, Split tensile strength and flexural strength of concrete for 7, 14 and 28 days of curing. In this present investigation super plasticizer of 1.25 percentages by the weight of cement and polypropylene fiber of 0.3 percentages by the weight of cement is used as dosage.
