Kit shuttering for the construction of a wall with integration of the kit and method of constructing a wall using such a kit

This shuttering kit comprises a plurality of panels (10) of mineral material, these panels being separable from each other and being adapted to be arranged, by juxtaposition of their edge, in the same plane so as to form a wall (P1; P2; P3) from the wall; and a plurality of struts (20), each strut being separable panels and including first (21) and second (22) connecting portions which are rigidly connected to each other by a connecting portion ( 23) of the spacer. The first connecting portion of each spacer is adapted to cooperate by complementarity of shapes with a portion of the edge of one or more of the panels forming a first wall of the wall while the second connecting portion of each spacer is adapted for cooperating with a second face of the wall, so as to fixedly hold in place the first and second walls, with the interposition therebetween of a shuttering space with a filling material.
