The purpose of this study was to analyze the influence of retarder, fiber and admixture on durability properties of repair mortar mixed MPC(Magnesia phosphate composite). The test results showed that the resistance to freezing-thawing and chloride attack of MPC repair mortar with fibers and fly-ash were greater than those of MPC repair mortar without fibers and fly-ash.
