Abstract

This article addresses recent research developments in calcium sulphate based building materials (such as gypsum, CaSO₄  ·  H₂O). They are based on an investigation of the hydration process of hemihydrate ( CaSO₄ · 0.5H₂O) and the resulting properties of dihydrate ( CaSO₄ · 2H₂O) and anhydrite ( CaSO₄). Also the development of new CaSO₄-H₂O based light-weight composites is presented. Finally, an additional functionality of CaSO₄-H₂O materials, viz. their air purifying capabilities, is addressed.

Key words:

CaSO₄ · 2H₂O system; hydration process; ultrasonics; thermal properties; self-compacting; light-weight composite; air purification; photocatalysis
