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).
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.[PDF]

Use of recycled coarse aggregate in concrete Recent statistics show that the increasing demand of construction aggregate could reach 48.3 billion metric tons by the year 2015 with the highest consumption being in Asia and Pacific.Uses of recycled concrete ·
The mechanical properties of recycled aggregate concrete (RAC) incorporating carbonated recycled concrete aggregates (RCAs) have previously been reported.
At first blush, recycled concrete aggregate may seem a second-best solution because its use is being driven not by concrete performance requirements but rather by the requirement to create a more sustainable concrete. But as experience and knowledge is gained, this perception is quickly being
The development of compressive strength of recycled aggregate concrete at the age of 1,3,7,14,28, 56, and 90 days; the development of tensile & flexural strength at the age of 1,3,7,14 and static modulus of elasticity at the age of 28 days are investigated.[PDF]
