Abstract This paper presents some research results on characteristics and durability of magnesium phosphate cement-based material, such as strength, coefficient of thermal expansion, drying shrinkage, corrosion protection, deicer-frost resistance, abrasive resistance and strength loss while soaking in water or 3% NaCl solution. Experimental results indicate that MPB materials posses high deicer-frost resistance, high abrasion resistance and high corrosion protection for reinforcing steel. In addition, the MPB materials have good compatibility and bond with old concrete, and very low drying shrinkage. However, for the MPB materials soaked in water or 3% NaCl solution for a long time, the strengh loss occurs. Laboratory and field studies show that the MPB materials are suitable for rapid repair of concrete structures. especially pavements aiport runways, bridge decks and key municipal roads, etc.
