What is a Concrete Test? (with pictures

Changes in slump height between batches of concrete can indicate a consistency problem. There are also slump requirements for different types of construction; low slump height concrete, for example, cannot be used to build roadways. Thus, the slump concrete test is both a quality control measure and a consistency measure.
