The practicle applicability of non-metallic reinforcing elements is usually mainly attributed to its strength and to its low- or non- sensitivity to the kind of atmosferic corrosion, experienced using steel reinforcing elements. This is particularly relevant where exposed to humid or otherwise aggresive environments.rnA range of other aspects deserve however a closer look, because less known, but advantages as disadvantages can be introduced, using this new and relatively unknown materials in structural engineering-Specific attention us given to the creep and relaxation behaviour of aramid-based bars, as well but in less detail investigated other aspect, which are important to be recognised.
