In the 1940's, potential of glass as a construction material was realized and improvement continued with the addition of zirconium dioxide in 1960's for harsh alkali conditions. To enhance durability of materials, new generation of glass fibres directed to improvement process. In this way, glass fibre reinforced concrete (GFRC) was started to produce for the satisfaction of different demands. Scientific studies and tests on the GFRC have shown that the physical and mechanical properties of the GFRC change depending on the quality of the materials and the accuracy of the production methods. GFRC can be used wherever a light, strong, fire resistant, weather resistant, attractive, impermeable material is needed. As technology advances, it is possibly expected to build the whole building and complex freeform with low cost. In recent years, the effect of glass fibres in hybrid mixtures has been investigated for high-performance concrete (HPC), an emerging technology termed, which has become popular in the construction industry.

“…Most previous studies investigated the bond performance between FRP bars/steel strands and concrete [ 32 , 33 , 34 , 35 , 36 , 37 ], and these studies mainly focused on bond strength (i.e., maximum bond stress) and the ascending and descending sections of the bond-slip curve. However, few studies focused on the residual section of bond-slip curves.…”

FRP bars and steel strands are widely used in civil engineering. In this study, three different types of high-strength reinforcement materials, carbon fiber reinforced polymer (CFRP) bar, glass fiber reinforced polymer (GFRP) bar, and steel strand, were investigated for their interfacial bond performance with concrete. A total of 90 sets of specimens were conducted to analyze the effects of various parameters such as the diameter of reinforcement, bond length, the grade of concrete and stirrup on the bond strength and residual bond strength. The results show that CFRP bars possess a higher bond strength retention rate than steel bars in the residual section. in addition, with the increase in bond length and diameter of the CFRP bar, the residual bond strength decreases, and the bond strength retention rate decreases. Furthermore, the bond strength retention rate of GFRP bars was found to be higher than that of CFRP bars. With the increase in grade of concrete, the bond strength and residual bond strength between GFRP bars and concrete increases, but the bond strength retention rate decreases. With an increase in bond length and diameter of the GFRP bar, the bond strength starts to decrease. Further, stirrup can also increase the bond strength and reduce the slip at the free end of GFRP bars. Moreover, the bond strength retention rate of the steel strand was found to be lower than CFRP and GFRP bar.

“…Due to FRP advantages compared to steel bars (high strength to weight ratio and durability), the use of FRP instead of steel as internal reinforcement for concrete elements has become increasingly common, especially in North America, as a means to avoid steel corrosion problems. Flexural behaviour of RC beams reinforced with FRP bars is investigated in previous researches [1][2][3][4][5][6][7][8][9][10]. Flexural ductility of RC elements with steel bars is calculated as the ratio of ultimate displacement to displacement at steel yield, while in the case of RC elements reinforced with FRP bars it can be calculated in a number of ways [11][12][13].…”

Fibre Reinforced Polymer (FRP) bars can be used as an alternate for reinforcing bars to avoid corrosion of steel. Samples of reinforced concrete beams cast with normal or steel fibre concrete (SFC), internally reinforced with Glass Fibre Reinforced Polymer (GFRP) or steel bars, are prepared and tested in this paper. Experimental results show that compressive strength of concrete increases with an increase in steel fibre (SF) ratio used in this study (from 0% to 1.5%). Also, the beams reinforced with GFRP bars have a lower initial stiffness and higher ductility than those reinforced with steel bars.
