Recycled Concrete Aggregate - an overview |

Recycled concrete aggregate (RCA) is the designation used in BS 8500-2 for recycled aggregate principally comprising crushed concrete. Designations of recycled aggregate other than RCA are of lower quality and may contain significant quantities of masonry which would preclude or limit their use in structural concrete. This is largely due to the potential for higher proportions of the masonry

PROPERTIES OF RECYCLED AGGREGATE CONCRETE

recycled aggregate as a component of concrete, there is a limit so that a coarse fraction of recycled aggre-gate whose absorption is not higher than 7%, and fine fractions whose absorption goes up to 13% [8], i.e. 10% can be used for the production of concrete. Accordingly, the absorption capacity of recycled aggregates should be treated as one of the basic properties, which is to be taken

Recycled Concrete as Aggregate for Structural Concrete

Recycled aggregate was made by crushing the waste concrete of laboratory test cubes and precast concrete columns. Three types of concrete mixtures were tested: concrete made entirely with natural aggregate (NAC) as a control concrete and two types of concrete made with natural fine and recycled coarse aggregate (50% and replacement of coarse recycled aggregate). Ninety-nine
