Freeze-thaw abrasion resistant cement pavement repair material, production process and application
The invention provides a freeze-thaw abrasion resistant cement pavement repair material, a production process and application. The freeze-thaw abrasion resistant cement pavement repair material comprises the following components: mortar, po42.5 cement, sulphoaluminate cement hydrochloride, latex powder, medium sand, a water reducing agent, magnesium aluminum silicate, fly ash, silica fume, a defoaming agent, a cement-based retarder, gypsum, calcium chloride and alum. Preferably, the mortar is prepared from the following components in parts by mass: 28 to 37 parts of mortar, 6 to 9 parts of po42.5 cement, 8 to 12 parts of sulphoaluminate cement hydrochloride, 3.4 to 4.5 parts of latex powder, 3 to 5 parts of medium sand, 2.4 to 2.9 parts of water reducing agent, 2.2 to 2.8 parts of magnesium aluminum silicate, 4.3 to 6.2 parts of fly ash, 3.2 to 4.4 parts of silica fume, 1.3 to 1.8 parts of defoaming agent, 1.6 to 2.3 parts of cement-based retarder, 3 to 4 parts of gypsum, 1 to 2 parts of calcium chloride and 0.8 to 1.6 parts of alum. The prepared repairing material has high freeze-thaw resistance and wear resistance, the durability of the cement pavement is remarkably improved, the service life is prolonged, and the repairing frequency and cost are reduced.
