20、611M. For concretewith a slump flow of 500 mm 20 in. or greater, fabricate test specimens as follows.7.2 Identify, position, and prepare the specimen container, and any related equipment, as described in the practice or test methodfor which the test specimen is required.7.3 Fill the pouring vessel w

22、flow into the container and to ensure an even distribution of concrete.7.5 During the filling process, position the lowest point on the rim of the pouring vessel no more than 125 mm 5 in. abovethe top of the container. If necessary, repeat the procedures in 7.3 and 7.4, without rodding the concrete

23、or tapping the sides ofthe specimen container, until the container is overfilled slightly above its rim.7.6 After filling, follow all subsequent specimen fabrication and testing procedures as specified in the practice or test methodfor which the test specimen is required.8.
