Description

Technical Field

[0001] The utility model relates to the technical field of concrete aggregate precooling, in particular to a high-performance concrete aggregate precooling device. Background Art

[0002] Concrete aggregates may be affected by high temperatures during transportation and storage. If these high-temperature aggregates are used directly in concrete making, the temperature of the concrete will be too high, affecting the strength and durability of the concrete. Precooling can reduce the surface temperature of the concrete aggregate and reduce the reaction rate between the aggregate and cement slurry, thereby making the working performance of the concrete better. The cement slurry in the concrete will shrink during the hardening process. If the aggregate temperature is too high, it will accelerate the hardening rate of the cement slurry, causing the concrete to shrink too quickly and easily crack. Precooling can slow down the hardening rate of the cement slurry, thereby reducing the occurrence of concrete shrinkage cracks.
