Description

Concrete slump detection device

Technical Field

The utility model belongs to the technical field of concrete slump detection, and particularly relates to a concrete slump detection device.

Background

The concrete slump mainly refers to the plasticizing performance and pumpability of concrete, and factors influencing the concrete slump mainly comprise grading change, water content, weighing deviation of a weighing apparatus, the dosage of an additive, the temperature of cement and the like, which are easy to ignore. Slump refers to the workability of concrete, specifically, to ensure the normal progress of construction, including water retention, fluidity and cohesiveness of concrete.

Workability refers to whether concrete is easy to construct and handle and is uniformly dense, a very comprehensive property including fluidity, cohesiveness and water retention. The workability is mainly influenced by water consumption, water-cement ratio, sand ratio, cement variety, aggregate condition, time and temperature, additive and the like.

The slump of the concrete is determined according to the structural section of the building, the content of the reinforcing steel bars, the transportation distance, the casting method, the transportation mode, the vibrating capability, the climate and other conditions, and is comprehensively considered when the mixing ratio is selected, and the slump is preferably smaller.

The existing concrete slump test method mainly comprises the steps of filling concrete into a trumpet-shaped slump barrel with an upper opening of 100mm, a lower opening of 200mm and a height of 300mm for three times, uniformly beating the concrete from outside to inside along the barrel wall by using a rammer after each filling, and trowelling after tamping. Then the barrel is pulled up, the concrete collapses due to the dead weight, and the height of the highest point of the concrete after the collapse is subtracted by the height of the barrel (300 mm), which is called slump. If the difference is 100mm, the slump is 100. However, the method needs to manually strike and beat the wall of the barrel, which wastes manpower, and is inconvenient to measure because the concrete after slumping is in a soil pile shape during measurement.

The present utility model has been made in view of this.
