What Makes Superplasticizers Super?

In concrete production, water and cement react to bind together fine aggregates (primarily sand) and coarse aggregates such as crushed stone or natural gravel. A relatively small amount of water is needed to initiate this chemical reaction (hydration) to transform the ingredients into concrete. 

However, additional water is often required to make the mix workable enough to be poured and finished, and the addition of too much extra water can decrease the strength of finished concrete. Reduced durability in concrete can lead to a premature need for repairs or replacement in the residential and nonresidential building sectors, as well as in such public projects as highways, streets, bridges, and dams.
