The invention discloses a long-acting anti-freezing
cement pavement repairing material, which comprises, by weight, 20-25 parts of 52.5
portland cement, 20-30 parts of low-temperature resistant anti-
cracking latex
powder, 0.5-1 part of
sodium bicarbonate, 1-2 parts of a
rust inhibitor and 3-5 parts of a long-acting high-efficiency water
reducing agent, 1-2 parts of low-cold-resistant low-
viscosity-resistant
cellulose 100 thousand units, 10-15 parts of
gypsum powder, 30-35 parts of water-washed and dried coarse sand and fine sand, 10-15 parts of
bauxite compound, 1-2 parts of
lithium sulfate, 25-40 parts of
quartz sand and carborundum, 5-20 parts of low-cold-resistant efficient air-entraining
powder, 5-6 parts of
polypropylene anticorrosive
fiber, 15-30 parts of 52.5 aluminum
sulfide systemcement, 18-20 parts of
dry powder mineral powder, 5-8 parts of
boric acid, 3-6 parts of
tartaric acid, 3-5 parts of organic
silicon and 20-25 parts of water. The repairing material is a powdery
polymer, has good acid and alkali resistance and
weather resistance and has low sensitivity to temperature, the strength is not influenced by low temperature, high
cold resistance is achieved, and the performance is stable, the strength rapidly and continuously grow, the material has strong repairing effect on original
cement concrete foundations and pavements of various
cement foundations in cold areas.
