Description

Technical Field

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

[0002] Concrete is a building engineering material formed by mixing cement, sand, gravel, etc. with water into a whole. After concrete is poured and vibrated, it can gradually set and harden mainly because of the hydration of cement. Hydration requires appropriate temperature and humidity conditions. Therefore, in order to ensure that concrete has suitable hardening conditions and its strength continues to increase, it is necessary to cure the concrete. In engineering, when pouring a concrete structure, it is necessary to take out a part of the well-stirred concrete to make several test blocks, and through these test blocks, the strength and other properties of the concrete structure are inspected. A concrete curing box is used for curing concrete test blocks. First, distilled water is injected into the box body and the box body is heated to a certain temperature, then the concrete test blocks are placed on the storage rack in the box body, and the box body is closed to carry out constant temperature and humidity curing on the concrete test blocks.

[0003] In the prior art, when curing concrete specimens, fog is generated through evaporation, which will condense into water droplets on the inner wall of the curing chamber, especially gather on the top of the curing chamber. As the volume of the water droplets becomes larger and larger, under the action of its own gravity, the water droplets drip down, and the concrete specimens will be dented by the dripping water droplets, which not only affects the appearance of the concrete specimens, but also reduces the quality of the concrete specimens.
