Dimensions in millimetres Figure 1 — Baseplate Dimensions in millimetres Figure 2 — Example of dimensions of a steelweighted collar 5 Test sample The sample shall be obtained in accordance with EN Clean the table and the cone and dampen immediately prior to testing, but keep free from excess moisture.
As the voice of the U.
NOTE The collar allows the test to be carried out by one person. Slump-test 3 Principle The slump-flow and t time is used to assess the flowability and the flow rate of self-compacting concrete in the absence of obstructions.

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. The deviation from flatness shall not exceed 3 mm at any point when a straight edge is placed between opposing sides and corners.
Fill the cone in one operation without any agitation or mechanical compaction, and strike off surplus from the top of the cone.

This standard is not included in any packages. The test is not suitable 123350-8 the maximum size of the aggregate exceeds 40 mm.
The surface shall not be readily attacked by cement paste or be liable to rusting. This European Standard specifies the procedure for determining the slump-flow and t time for self-compacting concrete. Organizations of all sizes and across all sectors choose standards to help Copyright them achieve their goals.
For further information on our subscription products go to Email: If the t time has been requested, start the stop watch immediately the cone ceases to be in contact with the baseplate and record the time taken to the nearest 0,1 s for the concrete to first touch the mm circle After the flow of concrete has stabilized without disturbing the baseplate or concrete, measure the largest diameter of the flow spread and record as d1 to the nearest 10 mm.
The largest diameter of the flow spread of the concrete and the bx of the spread at right angles to it are then measured and the mean is the slump-flow. Users are responsible for its correct application. Find out more about British Standards by visiting our website at commercial publication and use.
If the difference 1 2 between d and d is greater than 50 mm another sample shall be taken and the procedure repeated. You may delete a document from your Alert Profile at any time.
The test is not suitable when the maximum 1230-8 of the aggregate exceeds 40 mm. 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. 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.

Prevent skin contact with wet cement or concrete by wearing suitable protective clothing. A number of test methods including this test are available for testing fresh SCC.
This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by Januaryand conflicting national standards shall be withdrawn at the latest by January For further information, email bsmusales.
These should address three key properties: If the plate is made from other materials, in-use performance test data shall be available which demonstrates long-term equivalence with steel plate. It is based on the slump test described in EN When the cone is withdrawn upwards the time from commencing upward movement of the enn to when the concrete has flowed to a diameter of mm is measured; this is the t time.
