Mix Design
Plasticizer
// Definition
A water-reducing admixture that improves workability without adding water, or reduces water demand by 5-12% for the same workability.
First-generation lignosulfonate-based admixtures. Largely superseded by superplasticizers for high-performance work.

Workability
The ease with which fresh concrete can be mixed, transported, placed, compacted, and finished without segregation.
W/C Ratio (Water-Cement Ratio)
The ratio of the weight of water to the weight of cement in a concrete mix. The single most important factor controlling strength and durability.
Superplasticizer
A high-range water reducer that can reduce water demand by 15-30%, allowing very low w/c ratios with high workability.
