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. As the voice of the U. The result is an indication of the filling ability of self-compacting concrete.
The construction of the plate shall be such as to prevent distortion. Organizations of all sizes and across all sectors choose standards to help Copyright them achieve their goals. If the t time has been requested, start the stop watch immediately sn 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 123350-8 to the nearest 10 mm.
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.
