Abstract

Abstract:

Based on the summary of hydration products,hydration rate,pore structure,fluidity and physical and mechanical properties of magnesium phosphate cement（MPC）,modification effect and action mechanism of mineral admixtures such as fly ash,slag,silica fume,red mud and metakaolin on magnesium phosphate cement were reviewed.MPC modified by mineral admixtures has excellent physical mechanical properties and economical.The indepth study of the following topics,such as water resistance,durability under severe conditions,hydration and hardening characteristics at negative temperature and modification mechanism of mineral admixtures need to be further studied,which would be helpful to promote the engineering application of MPC and its repair mortar in key projects.

Key words: magnesium phosphate cement, hydration hardening, mineral admixtures, hydration heat, pore structure
