3. INTRODUCTION Recycling is the act of processing the used material for use in creating new product. Aggregates obtained from recycling of construction and demolition waste. Recycled aggregate are comprised of crushed, graded inorganic particles processed from the materials that have been used in the constructions.
The performance of recycled aggregate material from construction and demolition waste can affect concrete material strength that incorporates recycled aggregate in high volume.

In this study, the recycled plastics are used in the concrete by partial replacement of coarse aggregate in concrete. The main purpose of this study is to investigate the properties of concrete such as workability, compressive as well as tensile strengths in the partial replacement of aggregate.
Among the construction waste that could be recycled, we can mention the aggregates resulting from crushed concrete. While the acquired knowledge about the use of recycled aggregates in new ...
What are recycled aggregates ? • Recycled aggregates are the aggregates produced from the processing of previously used construction materials such as concrete or masonry. • Recycled aggregates consists of hard, graduated fragments of inert mineral materials, including sand, gravel, crushed stone, slag, rock dust, or powder.
