Comparison between Glass Fiber Reinforced Polymer and Steel : Undergraduate Thesis

Kompozitni materijal od staklenih niti međusobno povezanih sintetskim smolom, skraćeno GFRP, pokazao je veliki potencijal u građevinarstvu. Ispituje se i koristi već 70 godina. Očituje se mnogim značajno povoljnijim svojstvima u usporedbi s drugim tradicionalnim materijalima za armiranje. U ovom radu uspoređena su osnovna svojstva GFRP šipki i čeličnih šipki te armirano betonskih uzoraka prethodno pripremljenih i čuvanih u zadanim uvjetima. Šipke su ispitane na vlak, savijanje, prijanjanje s betonom - Pullout test, te je proveden test na savojnu čvrstoću betonske grede armirane GFRP šipkama.Glass fiber reinforced polymer-GFRP has demonstrated great potential in civil engineering . It has been used already for 70 years. It offers a lot of advantageous properties comparing with other traditional reinforcing materials . In this paper basic specifications of GFRP and steel have been tested and compared on test specimens of GFRP and steel bars and concrete beam which were prepared and cured before the test in special conditions. Bars were tested on tension, bending and bonding test - by Pullout test. Test method used on reinforced concrete beam is test for flexural strength
