Experimental Study of Use of Partially Processed Recycled Coarse Aggregates in Concrete Production

Recycling is the act of processing the used material for use in creating new products. The use of recycled product is increasing with modernization in present scenario. The use of recycled aggregates in concrete can also be useful for environmental protection. Recycled aggregates are the materials of the future. The consumption of waste products in the manufacturing of new product is a challenging job. The natural resources will deplete in a short period and therefore the use of waste product is essential. There are a large number of old buildings and structures which needs demolition today. The reuse of that demolished waste is a good solution to deal with the difficulty of an excess of waste material. Aggregates play an important role in strength characteristic of concrete. This paper focuses on the possibility of use of recycled coarse aggregate in concrete as a new structural material. For that purpose a literature survey for use of recycled aggregate concrete is done. Recycled coarse aggregate (RCA) is obtained from demolished concrete rubble and different demolished work. The aim of this project is to determine the strength characteristic of recycled aggregate concrete using recycled coarse aggregate concrete by using different percentage of recycled aggregates in M25 Grade.
