Need more than one copy? If cement or concrete enters the eye, immediately wash it out thoroughly with clean water and seek medical treatment without delay. Proceed to Checkout Continue Shopping. 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.

This standard is one of a series concerned with testing fresh concrete. The test is not suitable when the maximum size of the aggregate exceeds 40 mm.

NOTE The collar allows the test to be carried out by one person. This standard is also available to be included in Standards Subscriptions.

Prevent skin contact with wet cement or concrete by wearing suitable protective clothing. Up-to-date lists and bibliographical references concerning such national standards may be obtained on application to the CEN Management Centre or to any CEN member.

It is based on the slump test described in EN Then measure the diameter of the flow spread at right angles to d to the nearest 10 mm and record as d to the nearest 10 mm.

Since SCC has to give satisfactory in-situ properties perfect filling of the mould and embedment be the reinforcement, homogeneity and full compaction without vibration, the proper methods for testing the fresh SCC are very important.

The t time is a rn of the speed of flow and an indication of the relative viscosity of the self-compacting concrete. As the ne of the U. 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. 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.
