Abstract
The epoxy resin polymer cement mortars with excellent performances were made up through modifying ordinary Portland cement with emulsified epoxy and micro-fine slag. The microstructure of the epoxy resin polymer cement materials was studied and their hydration and hardening characteristics were discussed by means of modern analysis measures such as SEM, XRD and Hg-intrusion micromeritics. The experimental results indicate that the series effects of water-reducing, density, pozzolanicity, filling and solidification crosslinking through the action together with epoxy organism and micro-fine slag endowed cement-based materials with perfect performances. The main hydration products in the system are C-S-H gel and hydrated calcium aluminate. At later age, AFt can be in existence, and no Ca(OH)2 is found. When epoxy resin is solidified, the organism is in a network structure. In the micro-pore structure of hydrated cement with modified epoxy and fine slag, big harmful pores were fewer, more harmless abundant micro pores were and the possible pore radius was smaller than that of ordinary Portland cement.
