Analysis of the properties of masonry mortars made with recycled fine aggregates for use as a new building material in Cuba

This paper details the research work carried out on masonry mortars produced employing recycled aggregates in 100% substitution for natural sand aggregates. The main objective of the work being the validation of the resulting recycled aggregate mortar for use as a new construction material in Cuba....
