The effect of various sulphate solutions on the strength and other properties of cement mortars at temperatures up to 80°C

The results indicate that small rises in temperature can reduce and often prevent deterioration of Portland cement mortars in sulphate media, although rises in temperature cause loss of strength in other cements due to changes in crystal structure. The resistance of mortars to the more aggressive magnesium and ammonium sulphates at higher temperatures and the small expansion which occurs above 40°C are conclusively demonstrated.
