(1) The bonding, crack resistance, deformation resistance, frost resistance, corrosion resistance, abrasion resistance and other properties of the repair mortar are greatly improved compared with ordinary cement mortar, which can be adapted to the repair of holes, honeycomb, pockmarks and other defects of concrete of different strength grades;
(2) It can form a repair layer with good durability. When used in outdoor exposed natural environment, the good durability of repair mortar can ensure the long-lasting engineering repair.
(3) It has high abrasion resistance and can withstand the wear and tear of a large number of vehicles and pedestrians, effectively extending the service life of the road surface;
