Description

Technical Field

[0001] The utility model relates to the field of building construction inspection, and particularly relates to a concrete slump detection device. Background Art

[0002] The concrete slump is an important index to measure the workability of concrete. The fluidity, cohesiveness and water retention of the concrete mixture are measured through the slump test. A trumpet-shaped slump bucket is used, and the concrete is filled into the slump cylinder in three times. After each loading, the rammer is used to strike evenly from the outside to the inside along the barrel wall, tamped and leveled. Then, after the slump cylinder is vertically lifted, the height of the slump cylinder minus the height of the highest point after the concrete slumps is the slump value. Currently, on the construction site, the slump value is generally measured by construction workers with a tape measure. During the measurement process, since the body of the tape measure is prone to tilt during the process of pulling down and reading the value, it affects the measurement result of the slump value. Therefore, in order to solve the problem that the tape measure is prone to tilt when reading the slump value, a new type of concrete slump detection device is needed. Content of the Utility Model
