[0002] As a kind of hydraulic gel material, concrete, in its hydration hardening process, along with hydration heat release, moisture consumption and the heat exchange process with surrounding environment medium, multiple shrinkage deformation will be produced, and the shrinkage deformation of concrete is the main reason leading to the cracking of concrete structure. In order to prevent the cracking of concrete due to dehydration and shrinkage deformation in early stage, concrete structure needs to be cured and handled in early stage.

[0003] Concrete curing refers to a series of measures taken to maintain the humidity and temperature of concrete after pouring to support its normal hydration process, in order to make concrete harden uniformly, reduce cracks and improve strength. After pouring, watering curing will be carried out, which is one of the common curing methods. This process can keep the surface of concrete wet by spraying water, covering wet cloth or laying film on the surface of pouring body, prevent excessive evaporation of water, and the humid environment helps the hydration reaction of concrete, improves the uniform hardness and strength of pouring body.

[0004] At the same time, curing agent is usually added to the sprayed water, which can increase the humidity of concrete and prevent water evaporation during watering, effectively maintain the moisture of concrete, and also promote hydration reaction by maintaining humidity.

In steam curing project, a layer of high-humidity and uniform-temperature atmosphere is formed on the surface of concrete and surrounding environment, and high-temperature and high-humidity steam can prevent the surface of concrete from cracking or drying, and improve the durability of concrete.

[0006] The specific curing method can be adjusted and changed according to different projects and environmental conditions, such as the temperature of steam, the amount of sprayed water and the amount of curing agent in water. Different curing method combinations are needed in different regions. UTILITY MODEL CONTENT
