EPiC database - Gypsum plaster

This material is part of the free Environmental Performance in Construction (EPiC) Database. The EPiC Database contains embodied environmental flow coefficients for 250+ construction materials using a comprehensive hybrid life cycle inventory approach.

Gypsum plaster (traditionally known as plaster of Paris) is manufactured from gypsum rock and additives. The gypsum is heated to produce a dry plaster powder. It is then mixed with water to form a highly workable paste, which then hardens. It is a non-loadbearing material that is commonly used as a protective or decorative coating for walls and ceilings and for moulding and casting decorative building elements.

Gypsum plaster is often used to simulate other materials, such as timber, metal and stone, due to its ability to be formed into any shape, which can be easily sanded. It is also a core material for plasterboard and other plaster-based products, such as cornices. Alternative forms of plaster include lime and cement-based plasters.
