Use of Recycled Aggregate Concrete - IOSR Journals

If good quality aggregate is used for the production of new concrete, the recycled aggregate has no. influence on the compressive strength, regardless of the replacement ratio of natural coarse aggregate with. recycled aggregate. The same findings are found for concrete tensile strength (splitting and flexural).

Strength and Durability Evaluation of Recycled Aggregate

Durability of Recycled Aggregate (RA) can be influenced by coarse aggregate replacement ratio, concrete age, w/c ratio, and moisture content; generally, a lower w/c ratio generates a more durable concrete mix.
