Definitions
- the present invention relates to the field of lightened mortars for the facade and the floor. It relates more particularly to a method of continuous application by pumping a mortar based on a lightened material, an application device used in said process and the use of this device.
- the facade mortars layered on walls have a triple function of waterproofing, uniformity of said walls and aesthetic finish of the facades. They consist mainly of a mortar tempered with water and deposited in a thick layer before curing and drying. Soil mortars allow the realization of screeds and especially as self-leveling floor coatings.
- the deposition of these mortars can be achieved by pneumatic projection using a mortar pump.
- the amount of solid pore-forming compounds must be limited since the expansion of the mortar takes place in the chamber of the mixing pump: if the expansion is too rapid and too important, the foamed mortar occupies a too large volume and goes back to the dry mortar supply lines of the pump.
- Patent application DE 197 49 350 thus describes the addition of soluble catalyst precursor based on metal sulfate in the dry mortar composition. The catalyst itself is thus prepared in situ.
- WO 2007/134349 discloses a process for producing expanded inorganic foams using a solution of 15 to 35% hydrogen peroxide as blowing agent and a suitable catalyst for controlling the formation of foams under normal temperature conditions. and pressure, regardless of pH.

The simultaneous presence of blowing agent, catalyst and water causes the product to expand. The latter, once expanded, is pumped and can then be applied.

- tempered composition used hereinafter refers to a composition when mixed with mixing water, in the form of a paste, with a creamy texture, which can be used as a coating.
- the method according to the present invention advantageously makes it possible to obtain in situ, in the projection device, the formation of a lightened material by expansion. The expansion of the material takes place directly during its projection on the support.
- the chemical decomposition of the pore-forming agent makes it possible to continuously generate a large quantity of pores during the mixing step.
- the accelerated reactivity, on the one hand by the presence of the catalyst and, on the other hand, by the fact that the pore-forming agent is contained in a liquid solution makes it possible to expand the material continuously.

- the catalyst may be formed in situ in the projection device.
- a catalyst precursor is mixed with the powdery material composition, with the paste obtained after mixing, or is dissolved in the mixing water or the aqueous solution containing the blowing agent. This precursor is then converted into an active decomposition catalyst of the pore-forming agent based on peroxide, according to certain reaction conditions.
- the catalyst precursor may especially be chosen from water-soluble manganese (II) salts, such as manganese (II) acetate, manganese (II) sulfate, manganese (II) chloride and manganese nitride (II). These salts can be decomposed, in a basic medium, into insoluble compounds comprising manganese with a +4 oxidation state, such as MnO 2 or MnO (OH) 2 , which are known catalysts for the decomposition of peroxides.
