Kelly Ball Apparatus measures the workability of concrete. It is considered to be much simpler and faster than the slump test.
This field test determines the depth to which the apparatus will sink under its own weight into fresh concrete.
It can be used on site or in the laboratory.
It consist of a cylinder with ball-shaped bottom and 14 kg weight
stirrup handle graduated by ¼ inch.
Dimensions: 150 x 330 x 330 mm.
Weight: 16 kg.
In the construction sector, determining whether the concrete has workable properties is the most important criterion affecting the production and product quality, which is the next process. At this point, the Kell Ball test apparatus, which is used to measure whether the concrete has workability or not, has been specially designed for this process.
The main function of the Kelly Ball test apparatus is to provide information about whether the fresh, wet concrete is workable.
Kell Ball Test Apparatus Function
The Kelly Ball test apparatus, which first appeared in the United States in 1950, was also first used in the United States. In addition to being a preferred device since the year it was produced, it is among the most popular devices used during the experiment.
Thanks to this apparatus, which presents a slightly different version of the classical slump test, which is basically used in concrete testing equipment, the process performed is both cheaper and less costly, providing a great advantage for individuals and companies.
It is particularly remarkable in many respects, thanks to the fast execution of the process it performs. This device, which performs the test process at the place where the concrete is located, prevents time loss and also provides rapid results.
Thus, it is very easy to associate the data obtained as a result of the test with the Slump experiment and to compare the results, and it has been made suitable for use with different advantages.
This apparatus, which works in a very practical logic, also differs in terms of features compared to many devices.
The Kelly Ball test apparatus is a product designed and produced in accordance with the ASTM C 360 standard, which is basically one of the international standards. The device itself has a spherical system, while the lower part has a cylindrical shape.
Produced in the dimensions of 150 x 330 x 330 mm, there is a cylindrical area just below the device produced using metal products.
The main part is designed as a hemisphere and thanks to this feature, the depth in the penetration part can be easily measured.
The product has a metal arm to reveal the grading logic and is basically a product with a U profile. This product, which weighs 16 kg in terms of weight, has a 1/4 inch rated hand grip in terms of rating.
The Kelly Ball test apparatus, which can be used both on construction sites and in different land areas, can be easily moved to any point thanks to its light weight, and it provides an advantage to the user at this point. The fact that it is practical and easy to use is the most preferred reason for the product, and its exterior is covered with a special and rust-resistant material called cadmium in case of rust formation. In this way, it is possible to use it for a long time and does not pose any problems when used carefully.
