ABSTRACT:
A body (5) of set, initially pasty material, such as concrete, includes an electrically conducting path formed by a concentrated layer (6) of electrically conducting magnetizable elements, such as fibers (F) or granules (G), embedded in the initially pasty material and extending through at least a portion of the body (5). Electrically conducting terminal members (9) may be connected to the electrically conducting layer (6) at spaced-apart positions along the layer (6). A method of providing such a body (5) includes the steps of: (a) forming a body of the pasty material in which electrically conducting magnetizable elements (F) are dispersed, (b) applying a magnetic field to the body of pasty material to form from the magnetizable elements an electrically conducting layer embedded in the body of pasty material and extending at least through a portion the body (5), and (c) causing the body of pasty material containing the layer (6) to set. Before or after the setting of the body (5) of pasty material, electrically conducting terminal members (9), may be connected to the electrically conducting layer (6) at spaced-apart positions along the layer.
