Description

Technical Field

[0001] The utility model relates to the technical field of curing boxes, and in particular to a rapid concrete curing box. Background Art

[0002] Concrete is an artificial stone material made by mixing cementitious materials (such as cement), granular aggregates (such as sand, stone, etc.), water and admixtures and additives added when necessary in a certain proportion, and then evenly stirring, compacting, forming, curing and hardening. During the concrete construction process, the performance of concrete not only depends on the quality of its raw materials, the design of the mix ratio and the accuracy of the construction process, but also greatly depends on the subsequent curing measures. Therefore, it is necessary to use a curing box to cure the concrete. It simulates the curing conditions required for concrete in the natural environment in a controllable, stable and efficient environment, thereby ensuring that the concrete can complete the hardening process at the expected speed and quality.

[0003] Existing devices have some disadvantages during use. For example, existing curing boxes use heating pipes and humidifiers to cure concrete. In the static curing box, temperature stratification occurs due to natural convection where hot air rises and cold air falls. Temperature stratification causes uneven heating of concrete specimens or components during the curing process. Higher temperatures in the upper part will accelerate the hardening speed of the upper concrete, while lower temperatures in the lower part will slow the hardening process. This inconsistency will affect the overall performance and strength development of the concrete. Utility Model Content
