Abstract (en)
The element is characterised in that it is made from an injectable material which is shaped to delimit a hollow internal impression (1a) corresponding to the dimensions and shapes of the product to be obtained after casting the concrete, constituting a dead mould thereof. In order to allow stacking of the dead moulds and to solve the problem of drying the stacked products, the moulds comprise a peripheral edge (16) formed as a projection and vertical wings (1c). The wings (1c) are supported on the peripheral edge (16) of the mould situated below projecting from the bottom (1a), thus ensuring good circulation of air between the stacked elements. <IMAGE>
