1: Optimize the properties of concrete and prevent later cracking from affecting the quality.
During the concrete mixing process, the internal volume of the concrete's hydration heat increases, especially when mixing under high temperature conditions, the heat generated is higher. In subsequent curing or at low temperatures, thermal expansion and contraction will cause the internal volume of the concrete to Volume is reduced, a process that often results in cracks. Therefore, the initial pouring temperature of concrete should be low and reach the temperature limit of the building design unit to ensure the quality of the project. During construction, cold water is used to cool the concrete. The characteristics of concrete determine that it must be poured under certain temperature conditions to avoid wall deformation, cracking and other conditions caused by thermal expansion and contraction in the future. A professional concrete cooling system is a suitable choice to solve this problem, and it has become an important part of engineering construction.
2: Increase the transportation distance and extend the waiting time for materials:
During the construction process, due to the distance between the construction location of the mixing station and the construction site, if the summer weather temperature in the project location is 30-40°, the normal temperature pool water temperature may be 20-30°, and the cement The temperature of auxiliary materials such as mineral powder and mineral powder is as high as 50 degrees or even higher. If high-temperature water is used for concrete mixing, the exit temperature will be above 50 degrees; concrete solidifies as the temperature increases, so The subsequent transportation distance and feeding cycle will be greatly shortened, so cooling the water temperature of the mixing station will more intuitively increase the transportation distance, material waiting period and prevent the risk of solidification of tank trucks.
3: Lowering the temperature reduces the protection of the wear-resistant parts of the mixing host.
When the equipment is gathered into the main body of the mixing station for mixing, due to excessive temperature, the physical properties of the internal mixing wear-resistant parts soften. If the high temperature continues, the stone will rub against the high-temperature wear-resistant parts, and the wear rate will accelerate. On the contrary, Due to the drop in temperature of the concrete after cooling, the physical properties of the wear-resistant parts cannot be softened, and the rigid wear resistance will be reduced, thereby increasing the life of the wear-resistant parts.
The concrete cooling equipment of the mixing station is used to cool down the water used for concrete before use. It can change the high temperature of the concrete when it comes out of the machine, increase the solidification time of the concrete, increase the transportation distance, and change the state of the concrete to prevent later cracking from affecting the quality.
