Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a concrete slump testing device for building construction. Background Art

[0002] Concrete slump is a method and index for determining the workability of concrete. On construction sites and in laboratories, slump tests are usually performed to determine the fluidity of the mixture, and cohesion and water retention are assessed with intuitive experience. Slump is a quantitative index to measure the degree of concrete, which is used to determine whether the construction can proceed normally. The slump test method is: use a trumpet-shaped slump bucket with concrete. Tamp and smooth it, then pull up the bucket. The concrete will collapse due to its own weight. The height of the highest point of the concrete after collapse is subtracted from the height of the bucket, which is called the slump. Then use a caliper to measure the height.

[0003] Although the existing technology can accurately calculate the slump through the cooperation of the slump bucket and the caliper, it is inevitable that there are still some shortcomings in the actual use process. For example, the device lacks an integrated containing mechanism, so that the slump bucket and the caliper are inconvenient to carry as a whole and it is easy to forget to carry the caliper, which makes subsequent testing inconvenient. In order to avoid such problems, a concrete slump test device for construction is proposed to solve the existing problems. Utility Model Content
