The structural behaviour of reinforced concrete columns strengthened with a system made up offibre nets embedded in an inorganic stabilized cementitious matrix was investigated. Specimens with circularand square cross-section were cast and subjected to monotonic uniaxial compression to investigate the efficiencyof a Polypara-phenylene-benzo-bisthiazole (PBO) Fibre Reinforced Cementitious Mortars (FRCM)system in increasing both carrying capacity and ductility. The experimental results show that confinementwith PBO fibre produced a noticeable increment in strength and ductility, though the low mechanical ratios offibre considered were not always able to ensure hardening behaviour up to rupture.
