Abstract: | The aim of this work is to study the effect of temperature on the durability of mortars in a sulphate- magnesium-rich environment (5% MgSO4).The strength of mortars after 12 months of immersion in the sulphate solution is evaluated by visual observation, mass variation, compressive strength, and XRD analysis. No damage was observed on the samples exposed to the sulphate solution at 20, and 50 °C, except for mortars exposed to 5 °C which are very sensitive to the formation of thaumasite. Results show that high temperature improved the mechanical strength and do not necessarily accelerate the degradation due to magnesium sulphate. |
