Abstract

Superabsorbent polymers (SAPs) are able to absorb up to 1500 g of water per gram of SAP. Chemically speaking, SAPs are cross-linked polyelectrolytes which start to swell upon contact with water or aqueous solutions resulting in the formation of a hydrogel. This chapter gives an introduction into the production and specific properties of SAPs relevant for their use in concrete construction.
