The slump test is a method used to measure the consistency and workability of fresh concrete. It involves filling a conical mold with concrete, lifting the mold, and observing how much the concrete "slumps" or settles. The distance the concrete drops is measured, providing an indication of its fluidity and ability to be worked into forms. This test is commonly used in construction to ensure that the concrete mix meets specific requirements for strength and durability. A higher slump indicates a wetter mix, while a lower slump suggests a drier mix. Proper slump values help achieve the desired performance in structures.
