The Effect of Temperature on the Mechanical Properties of CA Mortar

Abstract:

The compressive strength and the flexural strength of CA mortar at different temperature conditions were all tested. We have found that temperature has great influence on the mechanical properties of CA mortar. As the temperature increase from -40°C to 60°C, its compressive strength decrease from 31.7MPa to 1.5MPa for CRTS I type CA mortar, while the same rule can be found to the flexural strength. Results also showed that as the content of asphalt in mortar increases, the temperature sensitivity of mechanical properties increases.
