“Testing of High-Performance Concrete using Recycled Aggregates”

Abstract

Abstract: Tons of waste is produced in the world on every day basis which sometimes gets really hard to manage and. The waste from demolished structures is one of them. Recycling waste consume energy and produces pollution that can lead to many adverse effects on the environment and human life. The disposal of waste is also very dangerous for the environment. Using waste materials like waste aggregates, broken bricks, stones and other material in concrete can help in eliminating the waste and save the environment getting polluted. It is also very much economical and encourages green concrete industry. The literature study consists of testing of high-performance concrete using waste aggregates by replacing 100 % natural aggregates. Also, silica fume and plasticizer are used as admixture to obtain more effective results. The tests were carried out on 3, 7 and 21 days of curing. The results were tallied using graphs between comparison of compressive strength and tensile strength of natural and recycled aggregates. The cement and natural aggregates and sand was obtained from a local store in a nearby market. The recycled aggregates were obtained from a nearby demolished building. The quantities were taken in a proper proportion according to IS codes to avoid any defects while constructing the cubes and while curing and performing various tests.
