This standard is one of a series on testing concrete.

EN 12350, Testing fresh concrete, consists of the following parts:

Part 1: Sampling and common apparatus
Part 2: Slump test
Part 3: Vebe test
Part 4: Degree of compactability
Part 5: Flow table test
Part 6: Density
Part 7: Air content – Pressure methods
Part 8: Self-compacting concrete – Slump-flow test
Part 9: Self-compacting concrete – V-funnel test
Part 10: Self-compacting concrete – L-box test
Part 11: Self-compacting concrete – Sieve segregation test
Part 12: Self-compacting concrete – J-ring test
Part 13: Bleeding test – Static and pressure

1 Scope

This document specifies the procedures for determining the static and pressure bleed of fresh concrete.

The tests are suitable for specimens having a declared value of the coarsest fraction of aggregates used in concrete (D_max) not greater than 40 mm. It can be carried out in the laboratory or on site.
