BS EN 12350‑5 is the fifth part of the multi-series standard which discusses the flow table test for testing fresh concrete.
BS EN 12350‑5 specifies a method for determining the flow of fresh concrete. The flow test is sensitive to changes in the consistency of concrete, which correspond to flow values between 340 mm and 620 mm.
Note-
BS EN 12350‑5 does not apply to self-compacting concrete, foamed concrete, no-fines concrete, or for concrete having a declared value of D of the coarsest fraction of aggregates used in the concrete (Dmax) of greater than 63 mm.
BS EN 12350‑5 on Flow table test for testing fresh concrete is applicable for:
The flow table test or flow test is a method to determine the consistency of fresh concrete. A flow test is used for assessing concrete that is too fluid (workable) to be measured using the slump test because the concrete will not retain its shape when the cone is removed.
BS EN 12350‑5 provides the tests which determine the consistency of fresh concrete by measuring the spread of concrete on a flat plate which will be subject to jolting.
BS EN 12350‑5 gives you the procedure which ensures that the hinged top of the table can be lifted to the correct limit of its travel and is then free to fall to the lower stop. Support the table in such a way that when the top of the table fails to the lower stop, there is a minimal tendency for the top to bounce.
