Definitions
- the present invention relates to a lightened insulating mortar and its use in the field of construction for coating and / or treating surfaces or walls of buildings, in particular facades, both for new constructions and for the renovation of existing constructions.
- Ble particularly relates to a mortar easily applicable to surfaces by means of usual applications, such as for example by pneumatic projection using a mortar pump.
- TE Outdoor thermal insulation
- ITE systems conventionally comprise an insulator on which one or more layers of facing plaster are applied. They are generally complex systems that are very thick.
- the insulating capacities of these systems are in particular a function of the choice of insulating material and its thickness. Sheets of expanded polystyrene with a thickness of between 20 and 500 mm are currently used. The greater the thickness of the plate, the better the insulation. However, too thick insulation results in a loss of floor space and also many additional costs. It is therefore necessary to find a compromise between a material with the best characteristics of soil and the most expensive weights.
- insulating plaster or mortar incorporates insulating materials such as expanded polystyrene beads or exfoliated vermiculite. They are usually applied in several layers. Even if they allow an improvement of the insulation of the surface on which they are applied, they do not make it possible to reach technical performances equivalent to those of the other techniques and system ITE, and do not make it possible to get rid of the plates insulation. Expanded polystyrene sheets used in conventional ITE systems have a thermal conductivity of about 37 mW / mK. In order for an insulating mortar to achieve similar thermal performance, it would be necessary for it to contain no heat.
- the present invention has sought to develop a lightweight insulating mortar usable for facade cladding to overcome the drawbacks mentioned above.

- Percentages of binder, polymeric or rheological adjuvant, leaching charges or other fillers and / or additives are given by weight or by volume relative to the total composition of the mortar. Only the percentage of pozzolanic agent is expressed relative to the amount of inorganic binder, since part of it is substituted by this agent.
- the mortar is lightened and has a density of less than 300 kg / m 3 in the cured state.
- the density measurement is performed after setting, hardening and drying the mortar.

- the pozzolanic agent is selected from metakaolin, blast furnace slags, fly ash, silica fumes.
