AB The present paper discusses the technical feasibility of using the fine fraction of recycled aggregate from concrete rubble to manufacture cement mortar and possible conditions. An initial study of the chemical and physical-mechanical characteristics of fines recycled from selected concrete showed that their high absorptivity and high sulfate content compared to natural limestone sands were the limiting factors to their in masonry mortars. As in the case of structural concrete, a blend of recycled and natural aggregate would appear to be suitable for masonry mortars. A study of the mix proportions and characteristics of mortars made with recycled concrete aggregate showed that up to 25% recycled aggregate can be used in cement-based masonry mortars with no significant decline in performance and no new admixtures or higher cement content requires.
