Ageing concrete infrastructures are known to be facing deterioration, especially regarding the corrosion of their reinforcing steel. As a solution, glass fibre-reinforced plastic (GFRP) bars now considered reinforcement alternative conventional steel, and design codes exist for designing GFRP-RC structures. However, there is need improve on addressing limited yield in GFRPs. Consequently, it su...

Abstract Glass fibers reinforced polymer (GFRP) were used to longitudinally and transversally 12 columns while the other 4 with steel or GFRP as reference specimens. This research dealt several parameters under different loading conditions, such reinforcing material spacing between ties. study aims find out ability of bear loads. In addition, investigate mode failure in these their appropriaten...

The challenges of machining, particularly milling, glass fibre-reinforced polymer (GFRP) composites are their abrasiveness (which lead to excessive tool wear) and susceptible to workpiece damage when improper machining parameters are used. It is imperative that the condition of cutting tool being monitored during the machining process of GFRP composites so as to re-compensating the effect of to...

In this work, a theoretical approach is proposed for estimating the minimum and maximum reinforcement ratios hybrid glass fiber reinforced polymer (GFRP)/steel-reinforced concrete beams to prevent sudden brittle failure as well compression of before tension reinforcements. Equilibrium equations were used develop method determining GFRP/steel ratio. A ratio was also developed based on equilibriu...

In this study, we report the effect of sizing glass fibres (GFs) with tetramethylpiperidine-1-oxyl (TEMPO)-mediated cellulose nanocrystals (t-CNC) to improve interfacial mechanical performance fibre reinforced polymer composites (GFRP). These nanoparticles are introduced at different concentrations yield a coating t-CNCs which (1) sparsely deposited low concentrations, and (2) uniformly self-as...

In recent years, even if Fiber Reinforced Polymer (FRP) composites have been widely used for strengthening of civil buildings, a new generation of materials has been studied and proposed for historical masonry construction. These buildings, mainly made of stone work, are common in many areas of Europe and Asia and recent earthquakes has been the cause of many catastrophic failures. The brittlen...

this study evaluates two different types of techniques for concrete hollow-block sections reinforced with traditional steel rebars and wire meshes, and compares their structural behaviour to that of an ordinary reinforced concrete beam section. the comparisons are based on the responses both before and after they were repaired with glass fibre reinforced polymers (gfrp). the specimens were subj...
