Definition
The Concrete Slump test is an empirical, instantaneous quality control check performed directly on the construction site before pouring concrete. It measures the consistency and workability of fresh concrete by filling a conical metal mold and measuring how much the concrete "slumps" or drops when the cone is lifted. A higher slump indicates a wetter, more fluid mix.
Practical Example
A transit mixer arrives at the site to pour a heavily reinforced column. The QA/QC engineer performs a slump test. The required slump is 120mm, but the concrete only slumps 60mm (it is too dry and rigid). The engineer rejects the batch, as pouring this stiff concrete into the dense column rebar will cause critical "honeycombing" defects.
Application in Superwise
QA/QC is a first-class citizen in Superwise. Engineers log the results of all Slump Tests directly into the Quality Control mobile module. If a batch fails, the system instantly notifies the Project Manager and triggers a Non-Conformance Report (NCR) linked back to the specific batch plant and concrete supplier.
