Resumo
A new process (patent applied) that works equally well with both plaster of mineral
gypsum and phosphogypsum for the preparation of gypsum components, UCOS, has been
developed. The process consists of the following steps: humidification of plaster by fine water
droplets, uni-axial compression, hydration reaction and drying. Strong hydrogen bonds develop
among the crystals together with adhesion provided by confined water that accounts for nearly
70% of the adhesion forces. By reducing the plaster to water ratio to close the minimum
necessary, new features are generated. An experimental house has been constructed, in which
walls and ceilings have been built of gypsum and phosphogypsum. Since phosphogypsum
potentially contain radioactive elements, the application of an activity concentration index to the
phosphogypsum employed in the building was carried out.
