Study on the aluminophosphate glass-rich cement

Li, J. / Li, S.Q. / Hu, J.S. / Liu-Biao / Wang, Q.

The phase composition, structural unit and hydration activity of glass-rich cement in CaO-Al₂O₃-P₂O₅-ZnO system were studied by means of XRD and IR analysis. The results show that the main phases in this cement are glass, L phase and CA. The early strength results from the hydration of glass and CA, and long-term strength from L phase. Aluminophosphate glass-rich cement has the characteristic of stable hydrates, early strength and steadily growing long-term strength.
