Abstract
In the frame of an extended research program dealing with the utilization of thermoplastic wastes in concrete, the effect of the above polymers on the reinforcement corrosion of concretes containing them as aggregates has been studied. Two types of thermoplastic waste were used, high density polyethylene and polypropylene. Measurements were carried out in order to investigate whether the corrosion behaviour of the rebars has changed due to the replacement of the conventional aggregates by the polymers, up to 240days of immersion of specimens in 3.5wt% NaCl solution. Results showed that the replacement of conventional aggregates by the two polymers studied does not worsen rebars’ corrosion behaviour.
