Abstract

Current procedures for characterization of recycled aggregates from construction and demolition waste can be time-consuming and costly, and hinder a greater breadth of re-use application. A multi-level Aggregate Potential (Physical) (AP(P)) scale is presented as a simple and cost-effective procedure for this characterization. To validate the AP(P), a group of mixed recycled aggregate samples were tested for composition, density, fines content, water absorption and freeze–thaw resistance. The results identify different quality ratings with potential uses, and simple treatments for higher value purposes. This procedure is purported to improve recycled aggregate manufacturing and secondary material markets, therefore contributing to a more circular economy.
