It has been proved that steel rebars embedded in concrete are exposed to degradation
with the time due to corrosion. Also, has been reported that polymer laminates suffer from
glass-fiber related stress-corrosion cracking in alkaline environments. Nowadays, there are a
number of glass fiber laminates commercially available but there are no sufficient data to
assess the right material system in terms of technical and cost points of views.
In this paper a set of tensile, bending and bonding test of alkali resistant (AR) glass and
steel rebars will be carried out in order to characterize these material systems. Strength and
modulus results will be reported. Finally, a case study related to aging of a concrete
reinforced beam will be described. Aging results for glass and steel reinforced concrete will
be shown.
