Recycled Concrete as Aggregate for Structural Concrete Production

Recycled concrete aggregate (RCA) is generally produced by two-stage crushing of demolished concrete, and screening and removal of contaminants such as reinforcement, paper, wood, plastics and gypsum. Concrete made with such recycled concrete aggregate is called recycled aggregate concrete (RAC). The main purpose of this work is to determine

Crushed Concrete Aggregates - Properties and Uses of Recycled

Strength variation of concrete produced from recycled aggregate is higher than concrete made from natural aggregate. For the recycled aggregate concrete, it would be necessary to add more cement in concrete made with 100% of recycled aggregate in order to achieve the same workability and compression strength as conventional concrete.

however, shows that the recycled aggregates that are obtained from concrete specimen make good quality concrete. The compressive strength of recycled coarse aggregate (RCA) is found to be higher than the compressive strength of normal concrete when used upto a certain %. Recycled aggregate concrete is in close proximity to normal concrete in ...

ABSTRACT

recycled aggregate concrete elements are similar to those of the reinforced natural aggregate concrete elements, but the load carrying capacity of recycled concrete elements is somewhat reduced. Little research has been conducted on punching shear and flexure behavior of reinforced recycled concrete slab elements.
