Description

Technical Field

[0001] This utility model belongs to the technical field of concrete curing equipment, specifically relating to a device for curing concrete shrinkage. Background Technology

[0002] Concrete is a hard and durable material capable of withstanding enormous weights, and is therefore widely used in the load-bearing structures of buildings, such as columns, beams, and foundations. It is one of the most important civil engineering materials in modern times. Concrete drying shrinkage curing is an important part of concrete curing, and its main purpose is to reduce drying shrinkage cracks caused by water evaporation in concrete, thus ensuring its quality. Therefore, concrete drying shrinkage testing is an important method to evaluate the phenomenon of concrete shrinking in volume due to water evaporation during the drying process.

[0003] Currently, it is inconvenient to simulate on-site concrete curing conditions in the laboratory for drying shrinkage testing because there are many on-site concrete curing methods, such as water spraying, film curing, and applying related film agents. However, water spraying is the most feasible and economical method in the laboratory. It requires manual spraying, which cannot guarantee uniformity. In addition, manual spraying requires removing the concrete test blocks from the curing chamber, which is a complicated and inefficient procedure. Furthermore, the water sprayed on the surface of the concrete test blocks cannot be collected and flows everywhere, which is not conducive to cleaning. Utility Model Content
