TL;DR
A slump test is the field measurement of fresh concrete's consistency: a standard 12-inch cone is filled, rodded, and lifted, and the inches the mix settles is the slump. Performed per ASTM C143, it verifies the load matches the specified workability, commonly 4 to 5 inches for residential flatwork.
What it means
A slump test is the field measurement of fresh concrete's consistency: a standard 12-inch cone is filled, rodded, and lifted, and the inches the mix settles is the slump. Performed per ASTM C143, it verifies the load matches the specified workability, commonly 4 to 5 inches for residential flatwork. A high reading signals water added beyond the design ratio, which weakens the slab, so testers pull the sample before any water goes in at the truck.
