Workability
The ease with which fresh concrete can be mixed, transported, placed, compacted, and finished without segregation.
Chemical Admixture
Liquid or powder additives used in small dosages (<5% of cement) to modify properties of concrete — workability, setting time, strength gain, or air content.
