Abstract
A high performance concrete, known as polymer concrete, made up of natural aggregates and an orthophthalic polyester binder, reinforced with non-metallic bars (glass reinforced polymer) has been studied. The material is described at micro and macro level, presenting the key physical and mechanical properties using different experimental techniques. Furthermore, a full description of non-metallic bars is presented to evaluate its structural expectancies, embedded in the polymer concrete matrix. Given the closed porosity obtained in polymer concrete, its microstructure continuity and organic nature of the binder, this material is highly protected against atmospheric conditions, corrosion and chemical attacks. The present research work concludes how the structural compatibility, between polymer concrete and non-metallic bars, is obtained in the monotonic bonding tests by providing higher adherence values than traditional reinforced concrete.
