“…On the basis of the results, it can be said that the reinforcement ratio has a significant influence on the flexural strength and failure mode of BFRP RC beams. Furthermore, there is good agreement between the results of these experiments and the results obtained for FRP RC flexural members using other types of non-metallic reinforcement [14,15,16]. Fig.…”

Basalt fiber-reinforced polymer (BFRP) bars are a relatively new material. Due to lack of experience in its use, behaviour of BFRP reinforced concrete (RC) members should be fully investigated. Furthermore, existing design codes for fiber-reinforced polymer (FRP) RC structures do not consider this type of reinforcement. This paper presents the results of an experimental and numerical study of the flexural behaviour of a series of simply supported BFRP RC beams under short-term static loads. The beams were varied in terms of the reinforcement ratio and the influence of this parameter was analysed. It had a significant effect on the stiffness and flexural strength of the beams. The members then were analyzed by the Finte Element Method. Good agreement between the results of the experimental and numerical studies were observed.

“…Lastly, since the surface geometries and mechanical features of FRP bars are different from steel bars, they bond differently to concrete than steel bars. Some researchers [14][15][16] predicted the structural behaviour of the FRP-RC system using the existing equations developed for the conventional RC with some modifications to account for these differences.…”

Geopolymer concrete reinforced with glass-fibre-reinforced polymer (GFRP) bars can provide a construction system with high durability, high sustainability, and adequate strength. Few studies deal with the combined use of these materials, and this has been the key motivation of this undertaking. In this study, the flexural strength and serviceability performance of the geopolymer concrete beams reinforced with GFRP bars were evaluated under a four-point static bending test. The parameters investigated were nominal bar diameter, reinforcement ratio, and anchorage system. Based on the experimental results, the bar diameter had no significant effect on the flexural performance of the beams. Generally, the serviceability performance of a beam is enhanced when the reinforcement ratio increases. The mechanical interlock and friction forces provided by the sand coating was adequate to secure an effective bond between the GFRP bars and the geopolymer concrete. Generally, the ACI 4401.R-06 and CSA S806-12 prediction equations underestimate the beam strength. The bending-moment capacity of the tested beams was higher than that of FRP-reinforced concrete beams from the previous studies.2

“…The second is the water absorption (Wambua et al, 2003). Although synthetic fibers such as glass fibers, have been used frequently in the past for reinforcing different types of composites (Alhozaimy et al, 1996;Tobbi et al, 2012;Almusallam et al, 2012;Aliha et al, 2012;Yao et al, 2013;Mazaheripour et al, 2013;Mohamed et al, 2013;Heidari-Rarani et al, 2014;Adam et al, 2015;Paul, 2003), to the best of the authors' knowledge, no previous attempt has been performed at manufacturing fibers for plastic reinforcement from the Diss plants. This work aimed to use the Diss fiber in strengthening of composite material.…”

This paper presents a novel composite material produced by a natural reinforcement subjected to tensile test. The used reinforcement is made of Diss fibers. The Diss (Ampelodesma mauritanica) is a Mediterranean wild plant. This fiber is characterized in tensile according to ASTM standard. The results obtained show that the fiber Young's modulus and the stress at break were very interesting and were similar to those obtained for some natural fibers such as sisal fiber. The composite was developed to study by three differing volume fractions of 20%, 30 % and 40 %.
