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 also available to be included in Standards Subscriptions. For further information, email bsmusales. The t time is a measure of the speed of flow and an indication of the relative viscosity of the self-compacting concrete.

Wash wet concrete off the skin immediately. The result is an indication of the filling ability of self-compacting concrete. The test is not suitable when the maximum size of the aggregate exceeds 40 mm. Customer Services If you need international and foreign standards from other Standards Development Tel: The use of SCC in practical concrete construction is steadily increasing.

If cement or concrete enters the eye, immediately wash it 123508- thoroughly with clean water and seek medical treatment without delay. NOTE The collar allows the test to be vs out by eh person.

The resulting values for r and R are given in Tables 1 and 2. Since SCC has to give satisfactory in-situ properties perfect filling of the mould and embedment of the reinforcement, homogeneity and full compaction without vibration, the proper methods for testing the fresh SCC are very important.

Check the top surface for horizontality using the spirit level.

The report may include: Measurement of the t time may be omitted if not requested. A list of organizations represented on this committee can be obtained on request to its secretary. A number of test methods including this test are available for testing fresh SCC. Check the concrete spread for signs of segregation and report under item 8, f in a qualitative way, e. These should address three key properties: 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.
