Description

Technical Field

[0001] The invention belongs to the technical field of engineering detection, and in particular relates to a concrete slump detection device for engineering detection. Background Art

[0002] Concrete slump mainly reflects the plasticization 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 the easily overlooked cement temperature will also affect the index. Concrete slump refers to the workability of concrete, specifically to ensure the normal progress of construction, including the water retention, fluidity and cohesion of concrete. At present, the conventional slump test method is: use a trumpet-shaped slump barrel with an upper opening of 100mm, a lower opening of 200mm, and a height of 300mm, fill it with concrete three times and tamp it. After each filling, use a tamping hammer to hit the barrel wall evenly from the outside to the inside for 25 times. After tamping, smooth it, and then pull up the barrel. The concrete collapses due to its own weight. The height of the highest point of the concrete after collapse is subtracted from the height of the barrel, which is called slump. Generally, multiple test data need to be collected, so multiple sets of slump tests need to be carried out.

[0003] At present, construction workers fail to fully comply with the specifications in their operations. When the barrel is lifted after filling and tamping, the concrete will stick to the barrel wall, forming a negative pressure adsorption force, thereby increasing the force required to lift the barrel, and there may be problems with abnormal test data due to lifting the barrel too violently.
