Description

Technical Field

[0001] The invention relates to the field of concrete construction, and in particular to a concrete cooling device and a mass concrete temperature control method. Background Art

[0002] Concrete is an important building material widely used in many fields. It is a mixture of cement, sand, stone and other materials. The reaction between cement and water will release a large amount of heat, which will cause the internal temperature of the concrete to rise. When the temperature exceeds a certain range, the concrete will produce thermal stress during the hardening process. This thermal stress may cause the concrete to crack and damage prematurely.

[0003] To reduce this risk, during the process of mixing cement and water in a mixing box, spraying cold water is often used to cool down the concrete. When the concrete is mixed and waiting to solidify, there is still a high residual temperature inside the concrete. If the concrete is cooled by spraying cold water, the cold water can only stay on the surface of the concrete and is difficult to enter the interior of the concrete, resulting in a large temperature difference between the interior and surface of the concrete, low cooling efficiency, and affecting the quality of the concrete.

[0004] In view of the above-mentioned related technologies, it is urgent to design and develop a concrete cooling device and a large-volume concrete temperature control method, which can quickly cool down the inside of the concrete during the process of concrete mixing and waiting for solidification, thereby improving the cooling efficiency of the concrete.
