Fiber‐reinforced polymer bars embedded in a resin concrete: Study of both materials and their bond behavior
Source abstract
Abstract
Abstract The study aims to analyze resin concrete (RC) bond behavior based on an isophthalic polyester resin, reinforced with nonmetallic rebars and is formed by pultruded glass fiber‐reinforced polymer (GFRP). The material is described at micro‐ and macrolevel by presenting the key physical and mechanical properties using different experimental techniques such as Hg porosimetry, scanning electron microscopy, and mechanical testing. Furthermore, a full description of GFRP bars is presented with regard to evaluation of its structural expectancies, embedded in the RC matrix. Given the closed porosity obtained in RC, its microstructure continuity, and organic nature of the binder, this material is highly protected against atmospheric conditions, corrosion and chemical attacks, requiring less cover for tensile reinforcing steel than Portland cement concrete. This research work concludes how the structural compatibility between RC and GFRP is obtained in monotonic bonding tests, providing greater adherence values than those of traditional reinforced concrete.
