Description

Concrete slump tester

Technical Field

The utility model relates to a concrete performance test technical field, in particular to slump apparatus.

Background

The slump of concrete mainly refers to the plasticizing performance and the pumpability of concrete, and factors influencing the slump of concrete mainly include grading change, water content, weighing deviation of a weighing apparatus, the dosage of an additive and the like. Slump refers to the workability of concrete, and the workability refers to whether the concrete is easy to construct and operate and the performance of uniform and compact, and is a very comprehensive performance, including fluidity, cohesiveness and water retention. Factors influencing workability mainly include water consumption, water-cement ratio, sand rate, cement variety, aggregate condition, time, temperature, additives and the like. When the mixing proportion is used for construction, the cement dosage is fixed, if the slump is not controlled, the water cement ratio is changed by using water at will, so that the strength is out of control, and therefore, the slump (consistency) of concrete (mortar) must be strictly controlled.

At the present stage, an instrument for measuring slump of concrete is simple, and a horn-shaped conical cylinder with an upper opening of 100mm, a lower opening of 200mm and a height of 300mm is roughly used, concrete to be measured is poured into the conical cylinder, tamping and flattening are carried out by using a tamping hammer, a scraper is used for scraping, then the conical cylinder is lifted, the concrete generates a slump phenomenon due to self weight, and the cylinder height (the height of the highest point of the concrete after the slump is subtracted is called as the slump). However, when concrete is measured, the concrete poured into the conical cylinder is more, the concrete needs to be screeded for multiple times by a manual scraper, the scraper is prone to loss, the screeding treatment needs to be carried out for multiple times, and the measuring tape is not beneficial to measuring by using the measuring tape at the back.
