recycled aggregates having better surface texture. It is observed that 10% fly ash addition improves substantially the cube compressive strength (at all ages) of both natural aggregate concrete and recycled aggregate concrete.Flyash addition modifies the microstructure of the interfacial zone which leads to a better performance of the concrete.

Recycled Aggregate Concrete: Applications, Advantages ...

Recycled aggregate concrete (RAC) is produced in three major steps: Evaluation of Source concrete: The first step in production of RAC is to determine the quality of the source concrete. Properties and records of source concrete like strength, durability and composition are looked into for deciding the proper source concrete.

The test results showed that the use of recycled concrete aggregate (RCA) reduces the compressive strength and this reduction increases with the increase in percentage of the RCA. Maximum decrement of about 33 % in strength or about 67 % of compressive strength development occurs when 100 % of RCA was used as substitute to virgin coarse aggregate.

The states that do use recycled concrete aggregate (RCA) in new concrete report that concrete with RCA performs equal to concrete with natural aggregates. Most agencies specify using the material directly in the project that is being reconstructed. Recycling of concrete is a relatively simple process.

Recycled Concrete—A Source for New Aggregate

The recycled aggregate concrete showed somewhat better workability characteristics than conventional mixes although its modulus of elasticity and durability characteristics were lower. It is proposed that satisfactory concrete can be made by recycling concrete as aggregate where disposal problems exist or where natural aggregate is either ...
