AQUEOUS GYPSUM PLASTER-CEMENT COMPOSITION AND ITS USE
An aqueous gypsum plaster-cement composition comprises a hydraulic binder consisting of calcined gypsum and hydraulic cement in a weight ratio of from about 4:1 to about 2:1, an aggregate which comprises sand, a foam, a perlite, rice hulls or a mixture thereof, a superplasticizer comprising an air entraining agent, a retarder, and water in an amount of from about 0.4 to about 0.75 parts by weight per part of binder, with the proviso that the gypsum plaster-cement composition contains essentially neither a pozzolana nor lime. The use thereof, a method of constructing buildings using this composition and the buildings obtainable in this way are also described.
L'invention concerne une composition aqueuse de ciment-plâtre-gypse comprenant un liant hydraulique constitué de gypse calciné et de ciment hydraulique selon un rapport pondéral compris environ entre 4:1 et 2:1, un agrégat qui comprend du sable, une mousse, une perlite, des écorces de riz ou un mélange de ceux-ci, un super-plastifiant comprenant un agent entraîneur d'air, un retardateur et de l'eau selon un volume d'environ 0,4 à 0,75 parts en poids par part de liant, à condition que la composition de ciment-plâtre-gypse ne contienne essentiellement ni pouzzolane ni chaux. Un procédé de construction de bâtiments et les bâtiments obtenus au moyen dudit procédé utilisent ladite composition.
