PARTIAL REPLACEMENT OF COARSE AGGREGATE WITH DEMOLITION WASTE

Abstract

In India and other nations, many concrete buildings are destroyed. However, the amount of waste from demolition that gets recycled is minimal. This will cause significant environmental degradation and necessitate a sizable quantity of room for waste disposal. As a result, our idea attempts to reuse concrete from demolished building. We obtained the demolition waste for our study from the Shastri Park, MCD Construction and Demolition Waste Recycling Process Plant owned by Indo Enviro Integrated Solution Limited. Any concrete structure must be built with a lot of natural coarse aggregate. So, it may lower the cost of buying natural coarse aggregate by employing the demolition material. In our study, demolition material will replace the coarse aggregate at different mix proportion of 0%, 10%, 20%, 30%, 40%, 50%, and 100%. The cubes and cylinder were cast using a variety of mix proportions and allowed to cure for 7, and 28 days. After curing, the Split tensile strength, XRD and compressive strengths of concrete cylinders and cubes were examine.
