This document provides testing methods for self-compacting concrete using the J-ring test. The J-ring test involves placing fresh concrete into a mold surrounded by a metal ring with gaps. The test determines if the concrete can flow through the gaps under its own weight without segregation or blocking. Passing the J-ring test indicates the concrete is self-compacting.
