This European Standard (BS EN12350-9) specifies the procedure for determining the V-funnel flow time for self-compacting concrete. The test is not suitable when the maximum size of the aggregate exceeds 22,4 mm.
The V-funnel test is used to assess the viscosity and filling ability of self-compacting concrete.
A V shaped funnel is filled with fresh concrete and the time taken for the concrete to flow out of the funnel is measured and recorded as the V-funnel flow time.
.This apparatus is used to evaluate the segregation resistance of freshly mixed self-compacting concrete by the observation on the fl owing speed due to the difference of samples remaining period in the funnel. It consists of a funnel placed vertically on a supporting stand, having 10 litres capacity, stand mounted.
The upper edge of the funnel is smooth and reinforced, and the outflow orifice is equipped of an openable seal valve.
