Testing fresh concrete - Vebe test
This document specifies a method for determining the consistence of fresh concrete by means of the Vebe time. The test is suitable for specimens having a declared value of D of the coarsest fraction of aggregates actually used in the concrete (Dmax) not greater than 63 mm. If the Vebe time is less than 5 s or more than 30 s, the concrete has a consistence for which the Vebe test is unsuitable.
