A Study on the Relationship between the Performance of External Thermal Insulating Anti-Crack Mortar and Maintenance Time

This study tests the compressive strength and flexural strength of two different types of anti-crack mortars in a variety of maintenance time periods, draws diagram of change trend, and analyses the reason for these changes. The experimental results indicate: (1) the various performance of anti-crack mortar is strengthened with the increase of maintenance time in general, (2) cement plays an important role in the performance of anti-crack mortar, (3) 21-day maintenance is a key note of the change trend of compressive strength, and (4) the flexural strength of 15-day maintenance has much to do with the content of rubber powder.
