A Study on use of Waste Materials as Partial Replacement of Coarse Aggregate in Concrete

Abstract

Abstract Background: More development approaches more litter, more litter makes natural worries of harmful danger. The use of litter materials for future new products would be a cost-effective and realistic solution to this problem, reducing the tremendous pressure on the country's landfills. Reusing litter as development materials save regular assets, saves energy, diminishes strong waste, brings down air and water contamination, and brings down ozone-depleting substance outflows. The development area can start to recognize and benefit from the advantages of using trash and repurposed materials. Acceptable litter, reused and reusable materials, and strategies have all been explored in numerous studies. Scope and approach: Due to the scarcity and rising expense of raw materials, the use of shattered tiles, glass, granite in structural components is used in this study. Compressive strength, workability, unit weight, density, cost of concrete made of litter material will be tested in this study. A comparison of all test findings of concrete formed of litter materials with conventional concrete will be done to break down present practices in the building industry regarding litter use and reused materials. Key findings and conclusion: This study provides an early knowledge of the practice's current strengths and flaws to assist the construction industry in formulating appropriate policies governing the use of trash and reused substances as improvement materials. Nine Samples were used with different proportion and mixes and it was found that 10 % partial replacement of coarse aggregate with glass achieved 26.83 % & 6.39 % more strength than target mean compressive strength (fm) of M20 conventional concrete for 7 & 28 days respectively. 7 day density & 28 day density of concrete cube made with 10 % partial replacement of glass with coarse aggregate was 1.75 % & 0.45 % less than the conventional concrete, this make concrete light and gives more target mean compressive strength (fm) than conventional concrete. All Samples come under medium degree of workability. Slump values are directly proportional to percentage of replacement. Use of this type of concrete will also reduce the dead load of the structure by 0.45 %. Saving of 10 % cost of aggregate can done by using concrete made with 10 % partial replacement of glass with coarse aggregate.
