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.

  • 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.

It notably has a durability and an aging compatible with its use as a facade mortar, presenting no degradation or cracks at the end of the aging cycles described by the EOTA guide used for external thermal insulation processes with mortar and / or at the end of the artificial aging tests according to NF T 30-049, NF P 84-402 and / or EN1015-21 standards.
  • Two mortar formulations according to the present invention are made by mixing the various constituents given in Table 1 in a Hobart type mixer.
  • Composition 1 comprises a mineral binder consisting of a mixture of cement, metakaolin (pozzolanic agent) and aerial lime.
  • Composition 2 comprises a mineral binder consisting of a mixture of cement, slag (pozzolanic agent) and hydraulic lime.
  • Composition A1 Composition A2
  • the mortars are prepared by mixing the various constituents with water.
  • the fresh dough is poured into appropriate molds and then matured for 28 days (at a temperature of 22 ° C and 55% relative humidity) before undergoing final drying in an oven at 70 ° C for several days until stability of the mass of the sample (corresponding to the elimination of free water).
  • the thermal conductivity is then determined on 25x25x4 cm samples, using a TCA 300DT conductivity meter from Taurus Instruments GmbH, in accordance with EN NF 12664.
  • Mortar formulations not in accordance with the invention were prepared in the same manner as in Example 1, and are described in Table 3 below.
  • Composition C2 55 0.5 250
  • Composition C3 54 0.36 236
  • Table 4 Composition C1 serves as a reference.
  • the amount of expanded polystyrene beads increases in the formulation of the mortar, it is found that the thermal conductivity is improved since it decreases, to the detriment of the mechanical strength which falls below 0.3 MPa.
  • Composition C6 is a formulation comprising a large quantity of expanded polystyrene beads and also polymeric additives: the thermal conductivity is improved but the mechanical strength does not exceed 0.3 MPa.
  • the amount of metakaolin represents 7% by weight of the total composition: even if the thermal conductivity is improved with respect to the composition C5, the mechanical strength remains around 0.3 MPa.
