When the quality of concrete is detected in a laboratory, the detection of the concrete slump is one of the important detections, and the concrete slump refers to the workability of the concrete, particularly the normal operation of construction is ensured, wherein the concrete slump includes the water retention property, the fluidity and the cohesiveness of the concrete. The slump is measured by a quantitative index, and is used for judging whether the construction can be normally carried out.

At present, the method for detecting the concrete slump in a laboratory is as follows: firstly, a wet slump cone is placed on a non-water-absorbing rigid horizontal bottom plate, and then pedals on two sides of the cone are stepped by feet, so that the slump cone keeps fixed in position during loading; then, uniformly loading the concrete sample into the cylinder by 3 layers by using a small shovel according to requirements, wherein the height of each layer after tamping is about one third of that of each layer of the cylinder; then removing the concrete on the bottom plate at the side of the cylinder, and vertically and stably lifting the slump cylinder, wherein the lifting process of the slump cylinder is finished within 5-10 s; the whole process from the beginning of loading to the slump cone should be carried out continuously and should be completed within 150 s; and finally, after the slump cone is lifted, measuring the height difference between the cone height and the highest point of the concrete sample after slump, namely the slump value of the concrete mixture.

The existing method is operated manually, and because the duration is long in the whole process, the actual slump value of the concrete is influenced by the fact that the concrete is easily overflowed due to the fact that a person steps on a pedal with great effort, and the concrete is difficult to tamp manually; and lifting the slump cone is also time-consuming and labor-consuming, and height measurement deviation is easy to occur. Therefore, in order to solve the technical problems of large measurement error, time consumption and labor consumption caused by the prior art, the laboratory concrete detection device is provided.
