A concrete slump detection device and its detection method

Abstract

The invention discloses a concrete slump detection device which comprises a platform, a slump barrel and two slide rails, wherein the two slide rails are distributed on two sides of the slump barrel and fixed to the platform; a first slide block, a second slide block, a third slide block and a fourth slide block are arranged on the two slide rails respectively, two slide blocks are respectively connected with a first lifting rod and a second lifting rod, and the two lifting rods are detachably connected with the slump barrel; holes are formed in the lower ends of the two slide rails respectively, spring parts are arranged on the two sides of the slump barrel respectively, and the tail ends of the spring parts are detachably connected with the holes; the third slide block is connected with a first connection rod containing a first rotating shaft, the first connection rod is connected with a material shaking part, and a plurality of limiting clamp blocks are arranged on the lateral sides of the corresponding slide rail; the fourth slide block is connected with a second connection rod containing a second rotating shaft, the second connection rod is connected with a stopping plate, a humidity sensor is arranged at the bottom of the stopping plate, and scales are arranged on the corresponding slide rail. The concrete slump detection device disclosed by the invention can save more labor in detection, reduce artificial error and more greatly improve measurement accuracy.

Description

technical field [0001] The invention relates to the technical field of concrete detection, in particular to a concrete slump detection device and a detection method thereof. Background technique [0002] Concrete slump mainly refers to the plasticizing performance and pumpability of concrete. Factors affecting concrete slump mainly include gradation change, water content, weighing deviation of weighing apparatus, dosage of admixture and temperature of cement, etc. The slump of concrete should be determined according to the structural section of the building, steel bar content, transportation distance, pouring method, transportation mode, vibration capacity and climate. When selecting the mix ratio, it should be considered comprehensively, and the smaller one should be adopted. of slump. The basic test method of slump is to use a trumpet-shaped slump bucket with an upper mouth of 100mm, a lower mouth of 200mm, and a height of 300mm, pour concrete into it and compact it, and ...

Problems solved by technology

Some existing concrete slump detection devices often need to manually operate various links. It is easy to touch the concrete during the pull-up process, which affects the concrete slump shape, and the measurement process is also prone to large deviations, resulting in inaccurate measurement results. Repeatability is poor, so there is an urgent need for a concrete slump detection device that can solve the above technical problems
