A review on recent developments in the recycled aggregate concrete

Abstract

The economical and the best way to overcome the shortage of natural resources for the manufacture of products is recycling. There are many types of concrete produced around the world by reusing and recycling the materials. Recycled concrete is produced by replacing the materials of concrete partially using recycled materials. The Construction and Demolition (C&D) waste shall be used as recycled materials, which reduces the disposal of wastes. The disadvantage of this type of concrete is poor strength and durability. Researches have been going yet in the recycled concrete to overcome those disadvantages. This paper reviews the recent developments that were made by the researchers in the Recycled Aggregate Concrete (RAC). New methods have been introduced by many research programs to improve the mechanical and durability characteristics of RAC. The characteristics discussed in this paper are physical, chemical, mechanical, and durability properties of RAC.
