Abstract
A building element based on plaster which is manufactured by dry mixing sand and plaster, by dampening the mixture, by placing the damp mixture in a mold, and by compressing the mixture in the mold while the plaster hydrates in order to densify the crystal lattice of the plaster. The building element (10) includes self-alignment projections (14) on its top face (12) and a vertical groove (22) at one of its ends for the purpose of casting a liquid sealant, such as plaster.
Claims9
A method of manufacturing a building element comprising dry mixing a hydraulic binder chosen among plaster and cement and an inert granular fill mixture, dampening said mixture by adding a quantity of water thereto which is substantially equal to or slightly greater than the quantity of water corresponding to the Proctor optimum of the mixture, immediately placing the damp mixture in a mold, and compressing it in the mold for a sufficient period of time necessary for the binder to hydrate and for the resulting crystal lattice to densify, and removing molded mixture from the mold.
