Stackable shuttering block made of lightweight material. This block has the shape of a right parallelepiped comprising two vertical side walls 10, 11 connected via transverse partitions which delimit cells opening upwards and downwards and intended to receive the poured concrete; according to the invention, one 11 of the said side walls is cut out at right angles to each of the said cells 3 in such a way as to present a series of apertures 12 opening on one side of the block 1 and each designed to receive a spreader, and a set of spreaders of different widths is provided, the choice of the spreaders allowing the curvature of the block to be determined, by elastic bending deformation of the other side wall 10. <IMAGE>
