Recycled Concrete as Aggregate for Structural Concrete

A possible solution to these problems is to recycle demolished concrete and produce an alternative aggregate for structural concrete in this way. Recycled concrete aggregate (RCA) is generally produced by two-stage crushing of demolished concrete, and screening and removal of contaminants

Recycled Aggregates in Concrete • Aggregate Research

Recycled Aggregates (www.cement.org) — Construction materials are increasingly judged by their ecological characteristics. Concrete recycling gains importance because it protects natural resources and eliminates the need for disposal by using the readily available concrete as an aggregate source for new concrete or pavement sub-base layers.

Suitability Investigation of Recycled Concrete Aggregates

In developing countries, construction and demolition waste (CDW) is disposed to landfill, causing social, environmental, and economic crises. In these nations, CDW exponentially increase due to their rapid economic growth, industrialization, and urbanization. This paper aims to examine the possibility of recycling concrete waste for production of new concrete in Ethiopia.

The Importance of Concrete Recycling

Markets for Recycled Concrete . Aggregate base course (road base) The largest application of recycled concrete aggregate (RCA) is for the aggregate base course in road construction.This term refers to the center layer of the roadbed. A cross-section of pavement would show dirt, or subgrade, as the lowest of three levels, layered on top by aggregate base course, and finally capped on top by ...
