After concrete is poured, the concrete can be gradually set and hardened mainly as a result of cement hydration, and the hydration requires proper temperature and humidity conditions, so that the concrete must be cured in order to ensure that the concrete has proper hardening conditions and the strength of the concrete is continuously increased; concrete curing is the artificial creation of certain humidity and temperature conditions that allow the concrete to be normal or accelerate its hardening and strength growth. Concrete is therefore able to harden and develop strength gradually as a result of the hydration of cement, which requires certain temperature and humidity conditions. If the surrounding environment does not have the condition, the concrete needs to be cured manually. The concrete curing method comprises the following steps: firstly, natural maintenance: and (5) separately spraying water for maintenance and spraying a plastic film for maintenance. The former is covered with concrete with a straw mat or the like, and is kept wet by spraying water frequently. The curing time depends on the cement variety, such as ordinary portland cement concrete not less than 7 days and nights. The latter is suitable for tall structures and large-area concrete structures which are difficult to be maintained by sprinkling water, etc. the perchloro-vinyl resin plastic solution is sprayed on the surface of the concrete by a spray gun, a layer of film is formed on the surface of the concrete after the solution is volatilized, the concrete is isolated from the air, the evaporation of water in the concrete is prevented, the normal operation of the hydration of the cement is ensured, and the film can age and fall off automatically after the maintenance is finished. Secondly, steam curing: the concrete member is placed in a curing chamber filled with saturated steam or a mixture of steam and air to accelerate the hardening of the concrete in a high temperature and humidity environment. Also known as damp-heat curing. The curing method is to accelerate the hardening of the concrete by taking steam as a heat medium.
