Abstract
The invention relates to a concrete pillar, in particular a circular pillar made of reinforced concrete with a pillar base (12), a pillar top (16) and, optionally, a steel reinforcement fitted inside the pillar. In order to enhance flectional and buckling resistance, a flat strip (18) in the form of a helix is provided between the pillar base (12) and pillar top (16), extending over the pillar surface, and having a composite structure consisting of a plurality of substantially parallel-aligned carbon fibres, and a binder matrix which shear-resistantly binds the carbon fibres to each other. The flat strip (18) is attached to the pillar surface by one of its broad sides by means of an adhesive. The lead (h) of the flat strip helix is thus greater than the width (b) of the flat strip (18).
