Concrete slump test vehicle

Abstract

The invention discloses a concrete slump test vehicle. The concrete slump test vehicle comprises a test barrel, a handcart, a tamping mechanism, a measure mechanism and a cleaning mechanism; the table top of the handcart is provided with a flat plate with adjustable height and angle, three-dimension adjusting capability is provided, and levelling is facilitated; on the table top, a linear slide rail is provided with a first portal frame and a second portal frame, the tamping mechanism is arranged on the first portal frame, and the measure mechanism is arranged on the second portal frame; the cleaning mechanism is arranged on the flat plate and is cooperated with a blanking port on the table top for usage; and a concrete recovery barrel is fixedly disposed under the blanking port. The concrete slump test vehicle is applicable to on-site concrete slump test, the levelness of the test platform is adjusted according to the site, the measure result precision is guaranteed, tamping operation, demolding strength and the process are relatively standard, and support is provided for accurately measuring the concrete slump.

Description

technical field [0001] The invention relates to the technical field of concrete slump test tools, in particular to a portable concrete slump test vehicle that can realize standardized measurement. Background technique [0002] Concrete slump mainly reflects the plasticizing performance and pumpability of concrete. The main factors affecting concrete slump include raw materials, mixing time, transportation machinery, pouring speed, pouring time, etc. In addition, the amount of additives and easily overlooked cement Temperature also affects metrics. [0003] Concrete slump refers to the workability of concrete, specifically to ensure the normal progress of construction, including water retention, fluidity and cohesion of concrete. [0004] Existing conventional test method for slump: 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, then pull out the bucket, and the concrete wil...

AI Technical Summary

Problems solved by technology

[0007] The operation is not standardized enough and is completely controlled by personnel. For example, the density of tamping varies according to the strength of the operator. During the process of unloading the bucket, the concrete will stick to the wall of the bucket, forming a negative pressure adsorption force, which makes the test The sample is elongated in the height direction, causing secondary damage to the sample and affecting the test effect

[0008] Whether the test platform is level has an important impact on the test results. The existing test process is basically tested on the ground, and the level of the platform cannot be guaranteed.

[0009] Combining the above factors, the existing testing tools need to be improved
