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...
