From Mini-Cone Test to Abrams Cone Tests: Measurement of Cement-Based Materials Yield Stress Using Slump Tests

This article reports on a type of stoppage test, the mini-cone test, and its use for cement pastes and grouts yield stress measurement. Stoppage tests in civil engineering consist of measuring the shape of a fresh material deposit after flow occurred. The authors first review the Abrams cone test, used for concrete. They then describe the flow induced by a smaller cone test for cement pastes and grouts. In the first part of the study, the spread is theoretically linked to the plastic yield value. The proposed method is then applied to the Abrams cone and fresh concrete. The authors conclude that this study upgrades the mini-cone empirical test to a real but simple rheological tool that allows the user to access an intrinsic property of the tested material instead of measuring a test geometry and material density dependent slump value. However, the surface tension often neglected in civil engineering flow studies may sometimes be the engine of the flow or of its stoppage. The authors caution that the mini-cone test is only suitable for high slumps (greater than 20 cm).
