For concrete. In the concrete technology, plasticizers and superplasticizers are also called high range water reducers. When added to concrete mixtures, they confer a number of properties including improve workability and strength. Unless the mix is "starved" of water, the strength of concrete is inversely proportional to the amount of water added, i.e., the water-cement (w/c) ratio.
