Use of Recycled Aggregates in Construction

A novel aggregate (RPA) comprising recycled plastic was developed. The aggregate produced was lightweight, with a density ranging from 510 to 750 k kg / m 3 and absorption of from 2.7 to 9.81%. Other properties were comparable to aggregates of similar densities. Various composition RPA was used in concrete, and the resulting properties of both ...

Jan 07, 2019· How Concrete Is Recycled . Concrete is recycled by using industrial crushing equipment with jaws and large impactors. After the concrete is broken up, it is usually run through a secondary impactor and is then screened to remove dirt and particles and to separate the large and small aggregate.

Crushed Concrete Aggregates

Expanded clay lightweight aggregate. Structural grades concrete. Not available. Recycled Aggregates Recycled Concrete Aggregate (RCA) Crushed sound and clean waste concrete of at least 95% by weight of concrete with typical total contamination lower than 1% of the bulk mass. Class 1A RCA is a well graded RCA with no more than 0.5% brick content.
