Problems solved by technology

[0003] The way of manual tamping has a great influence on the measurement of concrete slump. The reason is that when the concrete tamping is not sufficient, there will be problems such as air bubbles, agglomerations and uneven mixing in the concrete mixture.
For this reason, a scheme combined with vibrating mechanical equipment is proposed to improve the problem of concrete vibrating and mixing; in addition, the existing method of measuring the slump of concrete uses a digital display ruler, which is used to measure the slump It is easy to disturb the concrete, and then affect the height after the collapse, resulting in low measurement accuracy. Therefore, this project proposes an improved method combined with infrared light measurement

Description

technical field [0001] The invention relates to the technical field of concrete slump measurement, in particular to an infrared measurement device for concrete slump. Background technique [0002] The conventional test method for the slump of plastic concrete is: use a slump barrel with a trumpet-shaped slump with an upper mouth diameter of 100mm, a lower mouth diameter of 200mm, and a height of 300mm, and fill it with concrete mixture three times. After filling, use a tamping rod to tamp 25 times evenly from outside to inside along the circumference of the wall of the barrel, and then smooth it out after tamping. After the slump bucket is pulled up, the concrete will slump due to its own gravity. The height difference of the highest point of the concrete mixture after the slump is subtracted from the height of the slump bucket (300mm) is called the slump. [0003] The way of manual tamping has a great influence on the measurement of concrete slump, because when the concret...
