Workability of Fresh Concrete | NL Scientific

Workability & Consistency
Vebe Consistometer is designed for use in determining the consistency and density of roller-compacted concrete. The test can be performed on both laboratory and field prepared freshly mixed concrete with a maximum aggregate aggregate size 22” (50mm) or less. In addition to roller compacted concrete,the device can be on cement treated, aggregates & soil cement type mixer. Meets ASTM C1170 Test Method for consistency and density determinations of roller-compacted concrete. Can be used on both laboratory and filed prepared mixes.

Workability & Consistency
This test method is a variation of the simple slump test and subjects the concrete to vibration after removal from the slump cone. The time taken for the concrete to be recompacted is taken as a measure of workability. The small vibrating table operates at a fixed amplitude and frequency, and in the test a plastic disc is placed into contact with the upper surface of the concrete. The test is completed when the lower surface of the disc has been completely coated with cement grout.
