The use of SCC in practical concrete construction is steadily increasing.
The largest diameter of the flow spread of the concrete and the diameter of the spread at right angles to it are then measured and the mean is the slump-flow.

The report may include: Check the concrete spread for signs of segregation and report under item 8, f in a qualitative way, e. It is desirable, especially in the case of new constituents or new concrete compositions, to test the consistence of fresh SCC before casting in place.
The construction of the plate shall be such as to prevent distortion. Nevertheless any test method should at least be correlated to the practical situation and give consistent results in order to provide reliable data for judgment of concrete workability. Customer Services If you need international and foreign standards from other Standards Development Tel: Fill the cone in one operation without any agitation or mechanical compaction, and strike off surplus from the top of the cone.
The test is not suitable when the maximum size of the aggregate exceeds 40 mm. Licences can cover as few or as many users as you wish. If you find an inaccuracy or ambiguity within a British Standard or other The knowledge embodied in our standards has been carefully assembled in BSI publication please inform the Knowledge Centre.
A version in any other language made by translation under the responsibility of a CEN member into its own language and notified to the CEN Management Centre has the same status as the official versions. If the plate is made from other materials, in-use performance test data shall be available which demonstrates long-term equivalence with steel plate.

Clean the table and the cone and dampen immediately prior to testing, but keep free from excess moisture. A list of organizations represented on this committee can be obtained on request to its secretary.

Bss standard is also available to be included in Standards Subscriptions. According to the results from this EU project, it seems no single test method can completely cover all three key properties. Place the cone centrally within the mm circle on the baseplate and hold in position by standing on the foot pieces or use the collarensuring that no concrete can leak from under the cone.

This standard is one of a series concerned with testing fresh concrete. Please first log in with a verified email before subscribing to alerts. Add to Alert PDF. Owing to its significant advantages in the improvement of construction quality and working environment, self- compacting concrete SCC has been widely accepted by the construction owners.
Subscription pricing is determined by: Standards Subsctiption may be the perfect solution. We have no document history for this standard. Then measure the diameter of the flow spread at right 123508 to d to the nearest 10 mm and record as d to the nearest 10 mm.
NOTE The collar allows the test to be carried out by one person.
