A Study on Mechanical Performance and Mechanism of Cement Asphalt Mortar

Abstract:

This paper studies the effects of proportion of emulsion asphalt and cement, sand gradation and sand-to-cement ratio on 28d strength of CA mortar solidified body according to compressive strength. Results show that compressive strength of CA mortar evidently decreases with increase of quality ratio of emulsion asphalt and cement, and increases with sand gradation attenuated. 28d compressive strength of CA mortar obviously reduces when the sand-cement ratio is above 1.4. Mechanical performance and intensity capability of CA motor solidified body are determined by microstructure of solidified body and content of free asphalt, encapsulation and cementation state of microstructure.
