Study on Strength and Durability of Recycled Aggregate Concrete

Abstract

It is very evident in today’s time to introduce the use of recycled aggregates in the construction business as demolition waste is increasing and the resources are depleting day by day which is leading towards huge amount of environmental degradation. The three main aspects of this are the conservation of natural resources, the increasing of demolition waste and the economical aspects. Though some countries have started using the waste for highway construction, it hasn’t been used otherwise because of the sufficient supply of good quality unused material. There are some parts of the world that use crushed concrete but it’s only because of the poor quality of local material and there Is now a push within the Indian cement and concrete sector to improve the industry efficiency, one aspect of which is the use of recycled materials. Most of the researches deal with the strength of the recycled aggregate concrete and very little attention has been paid to the behaviour in service. In general, this research emphasizes on the Durability of concrete containing RCA . As the most common failure occurs in reinforced structures the aim of the project is to focus on durability and compressive strength. This research consists of samples of concrete and focuses on the following: • To check the compressive strength of M 30 grade of concrete incorporating use of RA. • To analyse the durability of incorporated RA concrete by chloride penetration test.
