Research on Hardening Mechanism of Cement-Emulsified Asphalt-Epoxy Resin

This article researched the cementation and hardening mechanisms of cement asphalt emulsion and waterborne epoxy mortar by using the XRD, and heat of hydration testing methods. The results of this study show that the mixture of cement with epoxy and cement- asphalt-epoxy are endothermic reaction. There are occurring endothermic reactions between cement with epoxy. The waterborne epoxy resin and basic structure unit of ettringite [Ca3Al(OH)6•12H2O] were reacted and formed Ca-complex at earlier period of hydration.
