Abstract (EN): The present work refers to on experimental tests and a parametric study in four series of reinforced concrete slabs. Reference RC specimens, of minimum reinforcement (series MIN) and twice this (series N), are compared with strengthened specimens externally bonded with two unidirectional carbon-fibre-reinforced-systems (CFRP), an “in situ” cured system - prepreg sheets (series M) - and a prefabricated system - laminate (series L). RC slabs with or without pre-cracking of concrete are analysed. Strengthened specimen series (L and M) were designed to have similar resistant capacity to the reference RC specimen series (N). After discussion of results conclusions are put forward with regard to the behaviour of RC strengthened with CFRP as a solution to a practical problem.
