Method of manufacture of an element of construction, from a mixture of both applications, of water and a load

摘要

Method of manufacturing a building element from a mixture of plaster, water and a load such as sand, characterized in that it consists in adding an ester of silica to this mixture (10), for example, before the manufacture of the construction element by compression (12) of the mixture, the mould (14) and drying (16), the ester of silica polymerizing in the presence of water to form a siliceous network of a crystalline hydrophobic tangled with the crystal lattice of the gypsum formed by hydration of the plaster in the construction element.
