Concrete curing agent

Abstract

A concrete curing agent is prepared from the following raw materials in parts by weight: 9-11 parts of aluminium sulfide, 5-8 parts of chlorosulfonated polyethylene, 3-9 parts of industrial soap, 5-8 parts of ethanol, 7-10 parts of lauryl sodium sulfate, 5-7 parts of seconda-grade fly ash, 7-11 parts of 4-isooctyl phenol, 6-8 parts of corn protein powder, 3-9 parts of dehydroacetic acid, 4-8 parts of sodium tripolyphosphate, 2-5 parts of hydrochloric acid, 9-16 parts of methyl methacrylate, 3-8 parts of divinyl benzene, 5-10 parts of ammonium persulfate and 4-11 parts of ethylene glycol. The beneficial effects of the concrete curing agent are that, the concrete curing agent can be high-efficiency, water-saving, and convenient in construction, can be used in large area, and can be widely used in airports, highways, buildings and other aspects.

Description

technical field [0001] The invention relates to a 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's research a...
