- Abstract
Construction and Demolition Residues have become a complex-to-manage and expensive urban problem, so currently an environmental legislation is innovated in order to promote activities to mitigate it being the recycling one of the more accurate (it empowers the reintegration as second generation material for new use in construction). Considering the previous comments, some studies with mortars have been developed, where the natural aggregates are replaced by different percentages of residues, since there are not legislation or regulation that propose them. However, there are few investigations about the behavior of these concretes in fresh state, linked them with theirs properties in the posteriori hardened state. In this investigation, tests of properties in fresh condition (consistency, density and content of air) of mortars containing different percentages of recycled concrete aggregates as substitution of natural aggregates (10, 20, 30, 50 and 100%) and with different cement/sand rates (1:3.25, 1:4 and 1:4.74), have been realized. The results obtained show that mortars with recycled aggregates present a lower density, need more quantity of water to achieve the required consistency, and have higher air content than the reference mortars.
