“…GFRP bars have high modulus of elasticity, in the range of 35 GPa and 51 GPa. The modulus of elasticity of GFRP is higher than that of conventional steel reinforcement, approximately %20 [24].…”

“…The other advantage of GFRP is that it is a more cost-effective solution than other types of FRP bars. Because of high strength, lightweight, electromagnetic transparency, fatigue resistance of GFRP bars, it has an increasing trend among researchers [23,24]. On the other hand, GFRP bars have been used on a lot of buildings such as bridges, marine structures, offshore structures.…”

The SIFCON concrete reinforced with glass-fiber reinforced polymer (GFRP) bars can provide a construction system with high durability and strength. Slurry infiltrated fibrous concrete (SIFCON) is a new type of conventional fiber reinforced concrete. The aim of this paper is to evaluate the flexural and shear behavior of the SIFCON concrete beams reinforced with GFRP bars were evaluated under four-point bending and three-point shear tests. The parameters investigated were material type of longitudinal reinforcement (steel and GFRP), transverse reinforcement type (steel and mesh) and mesh reinforcement spacing (25 mm and 12 mm). For this purpose, a total of twelve SIFCON concrete beams with steel and GFRP bar as longitudinal reinforcement measuring 150x150x800 mm were cast. Moreover, stirrup and mesh reinforcement as transverse reinforcement are another main parameter of this study. The test results showed that the effects of longitudinal and transverse reinforcement type and mesh spacing on the strength, crack propagation, and energy dissipation capacity of RC beams under bending and shear were experimentally investigated. The use of steel longitudinal reinforcement in both four-point and three-point tests increased the bending moment and shear strength compared to beams with GFRP. Moreover, although the use of mesh reinforcement in reinforced concrete beams under four-point bending reduced the strength, it increased the strength in beams with GFRP. In the samples under the shear force, the use of mesh reinforcement in the steel reinforced group increases the shear strength, but the use of mesh reinforcement in the GFRP group decreases the shear strength.

The increasing demand for river sand, driven by infrastructure development, poses environmental challenges. The study aims to address the depletion of river sand by integrating sea sand as a fine aggregate in the production of Self-Compacting Concrete (SCC) through a Systematic Literature Review. Furthermore, it includes an in-depth bibliographic analysis of relevant literature using VOSviewer to generate network visualizations of author-co-citation and country-wise citations. The article offers diverse options for sustainable solutions to mitigate environmental impacts while meeting infrastructure demands. It focuses on assessing the durability of SCC incorporating sea sand through real-time monitoring with the Internet of Things (IoT) and employing artificial intelligence methods like PointRend and neural networks to study the properties of SCC utilizing sea sand. Subsequently, the study emphasizes the need to address river sand shortages in infrastructure development and provides insights for further research on enhancing the properties of SCC with sea sand.
