A COMPARATIVE STUDY OF CONCRETE MANUFACTURED BY REPLACING NATURAL AGGREGATES WITH RECYCLED CRUSHED AGGREGATES
Keywords:Recycled Concrete Aggregate, Replacement, Workability, Natural Aggregate
The construction industry is becoming increasingly dependent on the natural resources. Amongst all the materials, concrete has a significant adverse impact on environment. Most of the concrete waste generated is dumped onto marshy areas, along water bodies or onto landfills. Looking at the sustainability issues, recycling of concrete has become the need of the hour. Current research trends are focusing on making concrete “greener”. Efforts are made to make concrete greener by replacing its traditional ingredients with environment friendly, cost effective and readily available materials. Among all the alternatives available, the use of recycled concrete aggregate as a replacement of natural aggregate is very promising. This paper presents a study of concrete made from recycled concrete aggregate. Various tests were carried out as per Indian Standards to analyse the performance of M20 grade of concrete made by replacing natural aggregate with recycled concrete aggregate. Also a comparative study of various parameters of concrete manufactured with natural and recycled aggregates has been carried out and presented.
