Abstract

A long-lasting concrete curing compound comprises the following raw materials by weight: 7 to 10 parts of ammonium thiosulfate, 6 to 8 parts of ethylene-propylene-diene monomer rubber, 2 to 7 parts of fatty ester, 5 to 8 parts of sodium carbonate, 7 to 10 parts of sodium dodecyl-benzene sulfonate, 4 to 8 parts of sodium gluconate, 4 to 7 parts of periodate lignin, 7 to 11 parts of tributyl citrate, 6 to 13 parts of ethyl acrylate, 4 to 10 parts of azodiisobutyronitrile, 3 to 8 parts of benzyl alcohol, 8 to 11 parts of glycol dimethacrylate, and 4 to 8 parts of gypsum powder. The long-lasting concrete curing compound has the advantages that the action time is long; the water retention effect is high; the service life of concrete can be prolonged.

Description

technical field [0001] The invention relates to a long-acting concrete curing agent. Background technique [0002] After the concrete is poured again, it cannot be sprayed with water before the final drying period. The surface of the concrete will lose a lot of water during the hardening process, causing the concrete to shrink and produce cracks. This kind of crack is called plastic shrinkage crack. Once formed, it is difficult to make up , a great hidden danger to the safety of buildings, the traditional concrete curing methods include natural curing, atmospheric steam curing and high temperature and high pressure curing. However, with the increasing shortage of water resources, traditional methods are difficult to meet the needs of construction. Therefore, people have developed concrete curing agent. But the curing agent on the existing market has various shortcoming, can not satisfy people's use requirement, the curing agent of high performance is a direction of people'...
