This is measured by subjecting a fresh concrete batch with a slump test. The higher the slump of the concrete, the more fluid it is, and a lower slump results in a drier concrete mix. Concrete and mortar mixes that have a higher water content will have higher slump and lower water content results in a lower slump.
