Incorporation of fine concrete aggregates in mortars
Highlights ► It is feasible to use very fine particles from demolition of concrete in mortars production. ► These particles are a serious environmental problem that can be turned into an opportunity. ► Most of the more important characteristics in coating mortars performance improve. ► This is a contribution to reduce the need for dumping grounds and natural re-sources dilapidation. ► It also has benefits from an economical point of view.
Abstract This paper presents a study of performance evaluation of cement-based mortars incorporating very fine aggregates from recycled concrete. A series of standardized tests were performed during the experimental programme with the objective of improving the performance of the mortars in terms of strength, water absorption, shrinkage, and water permeability. The research results were very positive since some of the properties of most modified mortars improved, showing that it is feasible to use up to 15% of recycled concrete fines in mortar composition.
