PROCÉDÉ CONTINU DE FABRICATION D'UN MATERIAU À BASE DE LIANT HYDRAULIQUE ALLEGÉ PAR EXPANSION
The present invention relates to a method for applying, onto a substrate, mortar which contains a hydraulic binder and which is lightened by expansion, said method implementing a pump spray device including a mixing pump, an outlet pipe for said pump, and a spray nozzle attached to the outlet pipe, and including the following steps implemented continuously in the device: a) mixing an aqueous solution, containing a peroxide pore-forming agent, with a composition including at least one hydraulic binder, in the presence of a catalyst for the breakdown of the pore-forming agent, said binder being selected from among, or being a combination of: cement(s), in particular Portland cement; a pozzolan cement mixture optionally including fly ash, blast-furnace slag, silica fumes, and/or natural or calcined or synthetic pozzolans; aluminous cement; sulfoaluminous cement; belite cement; as well as the mixtures thereof, and/or hydraulic lime; and, immediately after, b) continuously spraying the resulting lightened mixture.
