Concrete Mix Attributes, Instructions and Slumps

Mar 19, 2019 · Workability: The concrete mix workability is the property that determines the mix capacity to be placed and consolidate properly, allowing to finish a product without segregation. Consistency: This property determines the mobility and slump of the concrete mix. This characteristic is measured in terms of slump, the higher slump values, the more manageable, and greater mobility will be obtained.
