Description

Technical Field

[0001] The utility model relates to the technical field of concrete detection, in particular to a slump tester for buildings. Background Art

[0002] At present, a slump tester is applicable to perform slump tests on plastic concrete with a slump of 1 cm - 15 cm and a maximum aggregate size not exceeding 40 cm. The maximum aggregate size should not exceed 40 mm. 1. Moisten the slump cone and the base plate, and there should be no clear water on the inner wall of the slump cone and the base plate. The base plate should be placed on a solid (non-absorbent) horizontal surface, and the cone should be placed in the center of the base plate. Then step on the foot pedals on both sides with feet, and the slump cone should maintain a fixed position during loading. 2. Evenly load the obtained concrete sample into the cone in three layers with a small shovel, so that the height of each layer after ramming is about one-third of the height of the cone. Each layer is rammed 25 times with a rammer. 3. Level the top of the cone with a small shovel. After removing the concrete on the edge of the cone and the base plate, vertically and evenly lift the slump cone. The lifting process of the slump cone should be completed within 5 - 10 s; the entire process from the start of loading to the lifting of the slump cone should be carried out continuously and should be completed within 150 s. 4. After lifting the slump cone, measure the height difference between the height of the cone and the highest point of the concrete specimen after slumping, which is the slump value of the concrete mixture. 5. Observe the cohesion and water retention of the concrete specimen after slumping.
