Definition & Meaning of "concrete slump test"

What is the "concrete slump test"?

The concrete slump test is a method used to measure the consistency or workability of freshly mixed concrete. It involves filling a cone-shaped mold with concrete, then lifting the mold away. The amount the concrete settles or "slumps" after the mold is removed is measured. This slump value indicates the flowability of the concrete, helping to ensure it is suitable for the intended application. The test is often used in construction to check whether the concrete mix has the right consistency for pouring or shaping, especially for tasks like paving, foundation work, and forming structures.
