<p>The invention concerns building blocks for the construction of concrete walls that also provides insulation. The block (20) having a rectangular body comprised of walls (22), (24), 26), (28) and (30) which define a first (34) and second (38) cavity vertically extending within the block (20). Parallel grooves (40a) and (40b) are formed in the inner face of at least one wall, say (22a), of the first cavity (34). These grooves (40a) and (40b) enable at least part of the wall (52) to be removed. When this block (20) is in position in a wall the first cavity (34) can be filled with poured concrete that can flow through the removed part of the wall (52) and to a first adjacent block (20) or (200). The second cavity (38) can be filled with insulating material. In this way, a wall with good shear strength and good insulation can be built.</p> |
