Concrete slump detection device

technical field

The utility model relates to a detection device, in particular to a concrete slump detection device.

Background technique

Slump refers to the workability of concrete, specifically to ensure the normal progress of construction, including water retention, fluidity and cohesion of concrete. The slump is a quantitative index to measure its level, which is used to judge whether the construction can proceed normally. Workability refers to whether the concrete is easy to operate and evenly compacted. It is a very comprehensive performance, which includes fluidity, cohesion and water retention. The workability is mainly affected by water consumption per unit volume, water-cement ratio, sand ratio, and several aspects including cement types, aggregate conditions, time and temperature, and admixtures.

At present, when the slump detection device is usually used for detection, there is no connection between the traditional slump bucket and the bottom plate, and the concrete will overflow from the gap between the bottom plate and the bottom of the bucket when the tamping rod is in the process of compacting the concrete in the cylinder , the existing market also uses bolts to fix the bottom plate and the slump bucket, but after many tests, the bolts and nuts will be bonded by concrete, and the slump bucket cannot be disassembled; Its insertion and tamping depth is difficult to control, thus affecting the test results.
