FIBRE CONCRETE WITH FIBREX FIBRES MADE FROM SCRAP STEEL STRIPS

This contribution contains several examples of fibre-concrete structures which use fibreconcrete with atypical FIBREX A1 steel fibres, which are made of scrap steel strips of the strength of 350 ~ 450 MPa. The steel fibres with rectangular cross-section are 25 mm long. More effective anchoring in the cement matrix is provided by flattening of the fibre ends. The production of the mentioned steel fibres is backed by the characteristics of the produced fibre-concrete. Some of them are presented in this contribution.
