Description: The Kelly Ball Apparatus was developed in the USA in the 1950s as an alternative method to the slump test. The simple and inexpensive test can be applied to fresh concrete on site more quickly than the slump test, and the results can be correlated with the results of the slump test.

The 6” (152mm) diameter hemispherical metal cylinder consists of a metal handle with graduated hand grips for depth of penetration measurement.
