Automatic steam curing process for concrete
A concrete automatic steam curing process relates to the technical field of concrete steam curing, and adopts the technical scheme that the concrete automatic steam curing process comprises the following steps: S1, drawing up curing parameters, establishing a simulation model according to physical and thermodynamic parameters of a concrete structure, and verifying and correcting the curing parameters according to a simulation result; s2, a steam-curing shed is manufactured and installed according to the size of the concrete structure; and S3, after concrete pouring is completed, the control system completes curing according to the steps of standing, heating, constant temperature and cooling according to the curing parameters, and the surface layer temperature of each surface of the concrete structure is controlled to be consistent in the heating and cooling stages. According to the method, the simulation model is established to correct the maintenance parameters, so that the probability of manually handling unforeseen circumstances is reduced, and temperature difference cracks caused by untimely manual adjustment are avoided; in the heating and cooling stages, the temperature change rate of each surface of the concrete structure is controlled to make the surface layer temperature consistent, and temperature difference cracks on the concrete surface layer are prevented.
