Definitions
- the present invention relates to a honeycomb structural brick comprising a magneso-silico-calcareous porous material and can be used in the construction of high insulation wall.
- Terracotta bricks called “monomur”, or cement, called “cinderblock”, honeycomb structure, are widely used for the construction of walls, floors, partitions or other elements of buildings.
- These bricks are usually composed of empty cells (not filled) more or less large, more or less different shape, to increase the thermal insulation.
- These structures are composed of cells of reduced size to limit thermal convection and have low wall thicknesses to limit the conduction effect.
- the interior space of the cells of these building bricks is usually empty. When a temperature gradient exists within a cell, the air contained in this cell moves by convection. The direct consequence is a decrease in the thermal resistance of the system.
- One of the solutions implemented to minimize the convective effects is to increase the number of cells, but this solution is limited by (i) a technical implementation of bricks more and more complex, (ii) quantities of material more (iii) the appearance of more important conduction phenomena.
- this inorganic material is due to its microstructure to give a "mechanical strength to air or vacuum", namely to trap air (or vacuum) so as to minimize the effects of convection.
- the document FR 2 876 400 describes the use of hollow bricks filled "with an insulating material based on porous product (s) in bulk".
- the so-called natural material for filling is based on expanded perlite or expanded vermiculite in which starch is used as a thickener.
- This document also mentions the use of other components such as colloidal silica, hydrophobic agents, or dispersed plastic.
- the disadvantage of this solution is the low mechanical strength of the agglomerates, which entails a risk of deterioration of these packing masses during transport and assembly of these elements. It should be noted the low cohesive power of this structure inducing particular risks of loss of material during drilling, cutting, ... walls for example. It is also worth noting the settlement of the grains several years after the laying of the building elements, which ultimately leads to the reduction of the insulating power. Also the use of organic binders or hydrophobic agent substantially reduces the thermal resistance of these materials and increases the risk of fire resistance.
- Such a structure has the disadvantage of having a low mechanical strength, which limits the reduction of the number of walls of the clay brick and entails risks of degradation of the porous material during the laying of the building elements. Therefore, a problem that arises is to provide a building brick that does not have the disadvantages mentioned above.

- micro structure of the porous material composed of nodules more or less spherical and interconnected by crystals having the shape of needles, result of a crystallographic growth occurring during a hydrothermal synthesis, is shown in Figure 1 It should also be noted the potential presence of unreacted raw material grains or during chemical reactions.
- the total porosity of the porous material can be measured using a mercury porosimeter.
- the thermal conductivity can be measured using a device of the type Paque Chaude Guarded at an average temperature between 0 and 70 ° C.
- the compressive strength can be measured by developing a cube of 100 x 100 mm 2 porous material and applying on the upper face thereof a pressure force while it is held against a horizontal metal plate. This force corresponds to the pressure (in kg / cm 2 or MPa) from which the material begins to crack.
- FIG. 2 shows the compressive strength curves of several porous materials with chemical formulations as described in the invention but with different operating conditions, in particular temperature (T), pressure (P), rise and fall ramps; in temperature (° C / min) and the duration (t) of the hydrothermal synthesis.
