Abstract
The concrete spacer serves to fix the distance between armouring (3) and formwork (4) on concreting. To obtain a satisfactorily tight concrete covering of the armouring (3), the surface parts (1, 2) of the concrete spacer according to the invention which come into contact with the unset concrete between armouring (3) and formwork (4) exhibit a roughness which corresponds at least to the particle size of the unset concrete and/or a profile which corresponds at least to this roughness and has grooves or ridges running parallel to the formwork (4). <IMAGE>
