Anti-dusting rapid repair material for cement pavement
The invention provides an anti-dusting rapid repair material for a cement pavement. The anti-dusting rapid repair material comprises the following components: pavement repair mortar, sulphoaluminate hydrochloric acid cement, polyoxyethylene, quartz sand, a curing agent, hydroxypropyl methyl cellulose, an early strength agent, an accelerator, polyvinyl alcohol, a water reducing agent, cellulose ether, anti-cracking fibers, sodium chloride, calcium chloride and lignin. Preferably, the pavement repairing mortar is prepared from the following components in parts by mass: 32 to 45 parts of pavement repairing mortar, 14 to 22 parts of sulfur aluminum hydrochloric acid cement, 2 to 3 parts of polyoxyethylene, 8 to 11 parts of quartz sand, 3 to 4 parts of curing agent, 1.5 to 2 parts of hydroxypropyl methyl cellulose, 1.2 to 1.4 parts of early strength agent, 0.7 to 1.3 parts of accelerator, 0.8 to 1.2 parts of polyvinyl alcohol, 0.9 to 1.4 parts of water reducing agent, 2.1 to 2.4 parts of cellulose ether, 1.4 to 1.8 parts of anti-cracking fiber, 2.4 to 3.2 parts of sodium chloride, 2.4 to 3.2 parts of calcium chloride and 1.2 to 1.6 parts of lignin. According to the invention, the pavement can be quickly repaired, and the effect of preventing dust rising can be realized.
