Synthetic fibres having a roughened surface are admixed to a matrix containing a hydraulic binder. The fibres are produced by drawing and stretching from plastic which contains a filler formed by inert small grains (2). The inert small grains (2) loosened by the stretching are removed from the fibre (1) by frictional action. In place of the inert small grains (2), voids (4) remain, from which torn small fibres (5) project. The surface of other small grains (2) which have not dropped out is exposed. The fibres (1) having surfaces effectively roughened according to the above are retained securely and without sliding in the matrix.
