The mold is lifted and the concrete allowed to spread. Land Use and Development. BASF Construction Chemicals In the test method, a sample of freshly mixed concrete is placed in a cylindrical mold without tamping or vibration. After 15 minutes, the mold is separated into three sections representing the top, middle, and bottom of the cylinder.
A nonmandatory appendix of ASTM C provides a procedure for a relative measurement of flow rate, viscosity, and stability.
