THE USEFULNESS OF CONSTRUCTION AND DESTRUCTION WASTE AS RECYCLED AGGREGATES IN CONCRETE

Abstract

Worldwide, a high proportion of generated total solid waste is Construction and Demolition
Waste (CDW), the majority of which ends up in landfills. It has been proposed that this type of waste has
potential for being recycled and reused as aggregates in production of fresh concrete, particularly for basic
usage. The present study explores how feasible it is to produce concrete with Recycled Aggregate Concrete
(RAC) derived from CDW combined with rubber, glass, and flakes. To this end, the study provides a general
discussion of the engineering properties of RAC and investigates how the properties of fresh and hardened
concrete are affected by the recycled material. To make it more impervious, RAC was subjected to treatment.
According to the findings, concrete of satisfactory quality could be produced with the recycled material
derived from a site-tested concrete specimen. Furthermore, the properties of compressive and flexural tensile
strength varied depending on the differences in size of RAC components, but with regard to compressive
strength, the recycled material in the freshly produced concrete was similar to normal concrete.
