Description

Technical Field

[0001] The invention relates to a microwave curing device and belongs to the technical field of concrete microwave curing. Background Art

[0002] Concrete is one of the ultimate structural materials in modern construction projects. Its strength, durability and stability directly affect the safety and service life of the project. In the curing and curing process of concrete, moisture management is crucial. The right amount of moisture can not only promote hydration reaction, but also improve the microstructure density of concrete, thereby enhancing its long-term performance. However, during microwave curing, due to the accelerated evaporation rate of water caused by microwave heating, insufficient moisture will occur. Lack of moisture will lead to the following four problems:

[0003] 1. Incomplete hydration reaction: Water is a necessary component of the hydration reaction. Insufficient water will limit the hydration of cement particles, resulting in reduced concrete strength;

[0004] 2. The microstructure is not dense: Lack of water will lead to insufficient formation of calcium silicate hydrate in concrete, thus affecting the density of its microstructure, increasing porosity, and reducing compressive strength and durability;

[0005] 3. Dry cracking: Concrete lacking moisture is prone to cracks in a dry environment, which reduces the durability of the structure and may affect its use function;

[0006] 4. Deterioration in long-term performance: The long-term performance of concrete, including freeze-thaw resistance and chemical corrosion resistance, are all affected by moisture management. Insufficient moisture will weaken the durability of concrete and shorten its service life.

[0007] Existing microwave curing methods often fail to effectively control the migration and distribution of moisture, resulting in unsatisfactory curing effects. Therefore, developing a device that can monitor and adjust the internal moisture state of concrete in real time has become an urgent need for current technological development.
