“…Concrete is mostly frequently used material in construction sector due importance ans special concrete such as self compacting concrete [11][12][13] and glass fiber reinforced concrete [8][9][10][14][15][16] for different applications.A tiny number of short and randomly dispersed fibers, such as steel, glass, synthetic and natural, can overcome cement concrete's brittle failure properties. This type of concrete can be used in situations where concrete has a vulnerability, such as low durability or excessive shrinkage cracking.…”

Investigators all around the globe are making unrivaled concrete by varying the proportions and admixtures. Fiber-reinforced concrete has various applications in structural components. Some of the fibers like glass, carbon, polypropylene, and aramid fibers give an improvement in generous properties like hardened, durability, stiffness, toughness, shrinkage. The purpose of this research is to investigate the properties of glass fiber reinforced high-performance concrete (GFRHC) for arriving high-performance trail mixes are prepared with cement replacement with silica fume (SF) ranging from 0% to 25%. An optimum mix is chosen in that constant 1.15 % cement is replicate with nano-silica. For that optimized mix along with nano-silica, glass fibers are induced at 1%, 2%, 3%, and 4% by weight of cement. 100×100×100mm cube moulds, cylinder moulds of 100×200mm, and beam moulds of 100×100×500 mm are prepared and cured for 7, 28 days then hardened strength are evaluated. The result shows that at 10% replacement of cement with silica fume at constant w/b ratio 0.31 shown 59.06 Mpa for Mix-3 and at 2% addition of glass fibers shows the 69.4Mpa, 9.57 Mpa, and 7.91 Mpa of compressive strength, split tensile strength, and modulus of rupture for Mix-8. The quality of concrete of all the mixes are is excellent at 2% addition of glass fiber UPV value is 5281m/s.

“…It is regarded as a promising material for replacing ordinary steel reinforcements. By combining FRP bars/tubes with the seawater sea-sand concrete, which is rich in chloride ions, good comprehensive performance can be achieved (Dong et al, 2020a(Dong et al, , 2021Gao et al, 2020;Xiong et al, 2021;Zhang et al, 2020). To date, numerous ways have been proposed in the last three decades to promote the application of FRP in civil engineering, mainly include using it as internal reinforcements (De Luca et al, 2010;Tobbi et al, 2014;Afifi et al, 2014;Hadi et al, 2016;Pantelides et al, 2013) and using it as external strengthening/confinements (Zeng et al, 2020;Wang et al, 2020;Hadi et al, 2015;Yu et al, 2017;Ozbakkaloglu et al, 2013).…”

In this paper, a novel arch-shaped BFRP tube with longitudinal BFRP bars pre-bonded on the inner wall is proposed and fabricated. It can provide strength in both circumferential and longitudinal directions and is suitable for the rapid construction of arch bridges in island environments by filling with seawater sea-sand coral aggregate concrete (SWCC) in situ. Ten SWCC-filled BFRP tubular arches were fabricated and tested under monotonic loading. Test variables include the wall thickness of the BFRP tube, the radius angles of the arch, and with or without pre-bonded BFRP bars. Test results showed that the failure modes of arches without BFRP bars were bending failure under the loading point. The ultimate bearing capacities were increased by 33.1% and 71.7% as the wall thickness increased from 2 mm to 3 mm and 4 mm, respectively. The failure modes of arches containing pre-bonded BFRP bars were bending-shear failure close to the loading plate. The ultimate bearing capacity of arches, which containing BFRP bars, with a wall thickness of 2 mm, 3 mm, and 4 mm increased by 215%, 248%, and 189%, respectively, compared with the specimens without BFRP bars. The integrity and ultimate bearing capacities of arches decreased with the increase of the radius angle and their failure modes exhibited obvious brittle damage characteristics. The proposed new type of arch has good prospects for application in the marine environment.
