Description

Technical Field

[0001] The utility model relates to the technical field of concrete slump detection and discloses a concrete slump test device. Background Art

[0002] Slump mainly refers to the plasticizing and pumping properties of concrete. The main factors affecting the slump of concrete are gradation changes, water content, weighing deviation of scales, and the amount of admixtures. The temperature of cement is also easily overlooked. The test method generally uses a trumpet-shaped slump barrel with an upper opening of 100mm, a lower opening of 200mm, and a height of 300mm. Pour concrete into the barrel and fill it in three times. After each filling, use a tamping hammer to hit the barrel wall evenly from the outside to the inside 25 times. After tamping, smooth it, and then pull up the barrel. The concrete will collapse due to its own weight. The height of the barrel (300mm) minus the height of the highest point of the concrete after collapse is called slump. If the difference is 10mm, the slump is 10.

[0003] Patent No. CN216350724U in the prior art discloses a portable concrete slump test device for highway engineering, comprising a support plate and a slump cone. A tamping box is fixedly connected to the top of the support plate, and a tamping stick is placed inside the tamping box. A measuring ruler is fixedly connected to the top of the support plate, and handles are fixedly connected to both sides of the top of the support plate. A lifting mechanism is provided above the support plate, and the lifting mechanism includes a lifting motor and a threaded rod. The output end of the lifting motor is fixedly connected to a first bevel gear. This utility model relates to the field of highway engineering technology. The lifting motor of this portable concrete slump test device for highway engineering rotates, allowing the slump cone to be quickly pulled out. The support rod and the fixing assembly cooperate to ensure that the slump cone is well fixed and remains perpendicular to the horizontal plane when raised, thereby reducing errors and making the test results more accurate. The slump cone can be unfolded, facilitating cleaning of the interior, and improving the practicality of the device.

[0004] However, the patents in the prior art have the following disadvantages:

[0005] (1) It is impossible to quickly install and disassemble the slump measuring bucket, which affects the efficiency of the experiment.
