Rehydration on high temperature-mortars based on recycled glass as aggregate

The incorporation of waste of different nature as components of mortars and cement concretes is a scientifically valid option that allows us to obtain a positive environmental balance in the manufacturing process of these construction materials. Considering the capacity of improvement of the thermal...

description The incorporation of waste of different nature as components of mortars and cement concretes is a scientifically valid option that allows us to obtain a positive environmental balance in the manufacturing process of these construction materials. Considering the capacity of improvement of the thermal properties provided by glass, this work approaches the recovery by forced rehydration of mortars based on recycled glass after undergoing a process of heating at high temperature. Its mineralogical by XRD, structural evolution by SEM, X-ray computed tomography and DTA/TGA along with its physical-mechanical properties has been analyzed. Results have shown that, although the initial influence of glass can lead to inconsistent results according to the dosage and alteration process suffered, the favourable effect of the crushed glass after a thermal degradation and the subsequent rehydration treatment is observed. The rehydrated material based on recycled glass develops a capacity of mechanical recovery 6.2 times higher than the conventional mortar.
