  • a plurality of connection elements is, moreover, provided to connect and maintain at a distance from one another, the first wall and the second wall, so as to form a filling space between them.
  • These connection elements are at least partly embedded in the first wall and the second wall and extend through the filling space.
  • structural reinforcements embedded inside the first wall and / or the second wall, can also be provided to reinforce the structure of the first wall and / or of the second wall.
  • An insulating wall can also be provided and be interposed between the first wall and the second wall. More particularly, the first wall comprises an internal face opposite the external face and on which the insulating wall is mounted at the level of a contact face of the insulating wall. The insulating wall is then kept at a distance from the second wall by a plurality of connection elements to form said filling space.
  • the building element forms a wall with integrated shuttering and insulation.
  • Such prefabricated building elements are generally manufactured in the factory, then are transported to a construction site with a view to making interior walls and / or exterior walls. Walls can thus be structural or non-structural. After installation of the construction element on the site, its filling space forms a shuttering which is filled with at least one hydraulic material, for example concrete so as to form the core.
  • This filling material which is intended to form the core, is generally concrete.

  • the most commonly used hydraulic binder is cement.
  • One of the drawbacks of cement is that it has a significant carbon footprint linked to its clinker content.
  • Clinker is obtained by firing a mixture of limestone and aluminosilicates. However, this firing, also called clinkerization, is generally carried out at a temperature of about 1450 ° C. This results in high energy consumption and significant greenhouse gas emissions, which is undesirable in the current climate context.
