The modern types of concrete are a mixture of aggregates, cement, water and optional additives and admixtures. In particular, polymer additives seem to be a promising type of component that can significantly change concrete and mortar properties. Currently, the most popular polymer additives include superplasticizers, latexes and redispersible powders.

Chemical additives can be added to concrete to provide greater plasticity, workability and earlier levels of strength than from normal concrete or to maintain concrete quality in challenging weather conditions. There are five distinct types of chemical admixtures.
