Gypsum Gypsum used as a main matrix in this project was calcium sulfate hemihydrate gypsum (CaSO4.2H2O), which was obtained from local market in Baghdad. CaSO4.H2O + 1H2O → CaSO4.2H2O Mechanical Properties Tests Impact Strength Impact resistance is a measure of the ability of a material or structure to withstand certain level of the application of a sudden load without failure.

An Alternative to Gypsum Plasterboard — the University

A range of mechanical and hygrothermal properties were investigated to establish the potential of a bio-based plasterboard. Standard test methods developed for gypsum plasterboard were used to establish the mechanical and hygrothermal properties, including; thermal conductivity, vapour permeability and moisture buffering performance.
