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.

“…Regarding more specific tests on the connection between FRP profiles and concrete parts, Gonilha et al (2014) [13] performed several push-out tests and simulations of hybrid systems for a girder with I-shaped GFRP beams and concrete. Six specimens connected with steel bolts and/or bonding were considered in Koaik et al [14], and I-shaped pultruded GFRP bolt-connected profiles with partial interaction can be found in Neagoe et al [15]. The specific performance of FRP-concrete sections was also experimentally analyzed by Zou et al [16].…”

In order to combat corrosion issues, several studies on progressively replacing steel reinforcement elements with composite ones have been conducted in recent years. Hybrid steel–concrete thin slabs in which the steel acts as formwork are also candidates for update in the coming years. Achieving a reliable connection between fiber-reinforced polymer (FRP) and cast-in-place concrete is key to promoting this technology. This study analyzed different connection systems and proposes the novel approach of embedding a flexible fiber fabric as a superficially distributed connector between concrete and FRP. Eight specimens with four different connection strategies were tested using an experimental modal analysis and a quasi-static three-point bending test. The impact of the connection system on the vibrational response, flexural ultimate load, moment response, neutral axis position, shear and dissipated energy was obtained and compared. The results show that the use of an embedded mesh increases the frictional mechanism and produces the best performance in terms of load-bearing capacity and ductility.

“…In addition, the bond coefficient and elastic modulus (E) of FRP were the main factors manipulating the GFRP-RC beam behaviour. Due to the low values of E and shear modulus (G) of FRP, the arrangement of GFRP profiles with concrete features to resist high loads using a stiffer hybrid structure was a good recommended solution [31][32][33][34][35][36][37][38][39][40][41]. From the above review, it can be concluded that most previous studies focused on the analysis of RC beams with GFRP bars.…”

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.
