Performance of cementitious renderings and masonry mortars containing recycled aggregates from construction and demolition wastes
https://orcid.org/0000-0001-6766-2736
Highlights Systematic literature review and meta-analysis on recycled aggregate mortars (RAM). Rendering mortars with RA generally present similar performance to control mortars. Masonry mortars with RA normally have greater bond strength than regular mortars. High potential for cement content reduction of mortars containing very fine RA. Fine RA is a technically feasible and cost-effective alternative to natural sand.
Abstract This paper presents a systematic literature review of 114 publications published over a period of 39years from 1977 to 2015, alongside a meta-analysis of collated data sourced from publications concerning the effect of incorporating recycled aggregates, from treated construction and demolition wastes, on the performance of cementitious renderings and masonry mortars. Several of the most relevant properties were evaluated regarding the mortars’ fresh state and their mechanical, physical and durability-related performance. The results suggest that an increasing content of recycled aggregates may reduce the performance of some of the masonry mortars, which can nonetheless be easily compensated, but most recycled aggregates mortars for rendering applications have shown comparable performance to that of conventional mortars and complied with the requirements of the European Standardization.
