The SCC Test: Inverted or Upright?

SCC has been standardized yet. One test that has been widely accepted by those working with SCC is the slump flow test method. The slump flow is used to evaluate the horizontal free flow of SCC in the absence of obstructions. First developed in Japan for use in assessment of underwater concrete, this method is based on ASTM C143, the test ......
