What is the height of the slump mold?

The height of the slump mold is specified to be 12 inches. This standardized height is crucial for conducting the slump test, which is a common method used to measure the workability or consistency of concrete. The slump mold, typically in the shape of a frustum of a cone, is designed with precise dimensions in order to ensure consistent results across various tests. The 12-inch height allows for a standardized volume of concrete to be assessed, which can help predict how the concrete will behave under working conditions.

Using this specific height ensures that the testing methods align with ASTM standards, enabling comparability in testing results and reinforcing the validity of the slump measurement in quality control and engineering practices.
