Background technique

Slump is a method and index for the determination of workability of concrete. In construction sites and laboratories, slump tests are usually performed to determine the fluidity of mixtures, supplemented by intuitive experience to evaluate cohesion and water retention. The slump is a quantitative index to measure the level of its degree, which is used to judge whether the construction can be carried out normally.

Test method for slump: use a slump bucket with an upper opening of 100 mm, a lower opening of 200 mm and a height of 300 mm, pour concrete into three times and fill it in three times. Hit 25 times, and after tamping, smooth it out. Then pull up the bucket, and the concrete will slump due to its own weight. The height of the highest point of the concrete after the slump is subtracted from the height of the bucket (300mm), which is called slump. If the difference is 10mm, the slump is 10.
