K-Slump Tester

This device is used to determine the workability and degree of compaction of fresh concrete after being placed in the forms.

It can be used for in-situ measurements or inside test molds and forms. Results can be correlated against the slump test.

The operation is very simple: insert the tester  into the concrete up to the level of the disc,after 60 seconds, a measuring rod in lowered onto the surface of the concrete and the K-slump is read directly on a scale.

The calibrated hollow tube has a dia. of 20 mm.
