Abstract

The fundamental behavior of the concrete materials has significant effects on its performance characteristics and, hence it can bring influences on the strength of the materials. This paper investigates the essential behavior of recycled aggregate materials recycled concrete aggregate materials that are manufactured from C&D wastes. It also evaluates its impact on the performance of concrete material, which is made from recycled aggregate as a substitute for conventional aggregate materials. Hence, the volume of C&D debris generated annually has been growing increasingly in most localities; there should be improvements in recycling and utilization of these materials.  The recycled aggregate materials manufactured from C&D debris were then used as a substitute for conventional aggregate materials at a rate range from 0% to 100%. Recycled aggregates from C&D wastes measuring 10 – 40 mm collected from recycling plants for mixing purposes. Different concrete grades are used to evaluate the suitability of the material for utilizing it in various civil engineering and construction projects. The paper examined the fundamental properties of concrete for the M30 design mix that ranges up to 100% substitution of recycled aggregate material and conventional aggregate material. The overall material properties have been tested. The concrete materials that are produced from recycled aggregate as a substitution were used for various tests that check the performance of the materials. As a result, it shows that a noteworthy enhancement of strength detected in the concrete sample cubes that contained recycled concrete aggregates rather than mixed C&D waste recycled aggregates (RA).

Methods

The data were collected through laboratory investigations on the samples prepared from recycled aggregate materials as a substitute for the natural aggregate materials and different replacement rates have been applied to check the suitability of the recycled aggregate materials from C&D waste materials to use in various civil engineering and construction perojects.
