Description

Technical Field

[0001] The utility model belongs to the technical field of slump detection, in particular to a concrete slump detection device. Background Art

[0002] 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, supplemented by intuitive experience to assess cohesion and water retention. Slump is a quantitative index to measure the degree of its degree, which is used to determine whether the construction can proceed normally. During the test, a trumpet-shaped slump bucket with an upper opening of 100mm, a lower opening of 200mm, and a height of 300mm is used. Concrete is filled in three times. After each filling, a tamping hammer is used to hit the barrel wall evenly from the outside to the inside for 25 times. After tamping, it is smoothed, and then the barrel is pulled up. The concrete collapses due to its own weight. The height of the highest point of the concrete after collapse is subtracted from the height of the barrel. The calculated result is the slump value.

[0003] From the operation process, it can be seen that in order to compact the concrete, the mixture is loaded into the drum in three layers, and the height of each layer is about one-third of the height of the drum. Each layer is compacted 25 times along the spiral line from the edge to the center with a tamping rod to ensure compaction. Manual compaction operation is required, which is time-consuming and laborious. Utility Model Content
