Recycled Aggregate Concrete Applications Advantages CONCRETE MADE FROM RECYCLED AGGREGATE

One such material is recycled aggregate concrete Fig 1 Concrete debris Manufacturing of Recycled Aggregate 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 concretewater absorbing recycled aggregate The goal of this production method is to reduce the standard deviation of compressive strength by maintaining a constant initial consistency for each concrete mixture while simultaneously controlling the development of rigidity which can be higher due to the water absorption of the recycled aggregate 2
