Research on Microstructure Structure Formation Mechanism of Cement-Emulsifying Asphalt and Waterborne Epoxy Cementing Materials

Article Preview

Abstract:

Cement-Emulsifying Asphalt and waterborne Epoxy (CAE) cementing materials meet requirement for paving in steel bridge deck pavement materials, which possessing good flexibility, high temperature stability and cohesiveness to steel plate, and the microstructure model and structure formation mechanism of CAE mortar was researching in this paper. The results of the study show that, CAE mortar forms the asphalt and epoxy interpenetrating network structure which connect with cement, and the forming process contains four stage, which is dispersedness, interaction, structure formation and strength development. This structure makes CAE concrete give full play to such characteristic, which is good adhesion of cement with asphalt and epoxy resin, good temperature stability and high bonding strength of epoxy resin, good toughness of asphalt.
