Summary: The study found that BFP was effective in reinforcing cementitious composites, while nanosilica enhanced the postcracking performance of high-volume fly ash- and slag-based mixtures under different loading schemes. Increasing the pellets' dosage improved the ductility of composites, and the pellet/matrix interface played a crucial role in the toughening mechanism of the composites.

Summary: Basalt fiber-reinforced concrete (BFRC) is a new type of fiber-reinforced concrete that has shown good mechanical performance. Basalt fibers (BF) have advantages over other fibers such as steel, glass, and carbon fibers in terms of comparable mechanical strength, higher durability, lower cost, abundant raw material supply, and environmentally friendly production process. The review paper discusses the properties of BF and BFRC, as well as the effects of BF length and dosage on the fresh, hardened, and durability properties of BFRC. It concludes that BF has the potential to replace conventional fibers in the industry.

Summary: This research focused on basalt FRP reinforcing bars as a non-corrosive alternative for traditional steel reinforcing bars in concrete structures. The study found that the tensile strengths of the basalt FRP reinforcing bars were consistent and exceeded those of comparable GFRP reinforcing bars. However, variations in tensile strength were observed due to differences in raw materials and production processes.

Summary: The feasibility of using liquid crystal display glass powder (LCDGP) instead of quartz powder (QP) in ultra-high-performance concrete (UHPC) matrix was discussed, showing that while LCDGP reduces packing density, it increases compressive strength due to pozzolanic reaction. However, excessive LCDGP content decreases mechanical properties.

Summary: The durability of basalt-fiber-reinforced polymer (BFRP) bars reinforced seawater sea-sand concrete (SSC) beams in simulated seawater and tap water was investigated. The tensile strength of the BFRP bars decreased with the immersion time and the environmental temperature, with a more severe decline in tap water. The failure mode of the BFRP-reinforced SSC beams changed from shear to flexural failure. Furthermore, a predictive equation was developed to estimate the flexural-load-carrying capacity of the BFRP-reinforced beams in actual oceanic environments.

Summary: Basalt fiber-reinforced concrete (BFRC) has excellent mechanical properties and durability. The addition of basalt fiber with specific dimensions can effectively improve the mechanical properties of concrete and enhance its resistance to chloride erosion and sulfate attack, while also increasing impermeability. Future research should focus on the mechanical properties and durability of BFRC under high temperatures and after damage, as well as the toughening mechanism of basalt fiber in hydraulic concrete.

Summary: Population increase and building construction contribute to environmental pollution through high carbon dioxide (CO2) concentrations. The depletion of traditional concrete materials necessitates finding sustainable alternatives, such as seashells, which can be used as cement replacements in concrete production. However, seashell addition can reduce concrete strength while improving other properties like porosity and absorption. Therefore, further research is needed to determine optimal conditions for utilizing seashells as renewable and sustainable concrete materials with lower replacement levels, which could contribute to reducing CO2 emissions.

This paper focuses on studying the flexural behavior of Concrete Filled Steel Tube (CFST) beams with DCLs. The results show that the flexural behavior of DCL CFST specimens is very similar to control CFST specimens, with minimal effect on ductility, stiffness, yielding capacity, and ultimate capacity.

The test results showed that changing the mode of failure from GFRP rupture to concrete crushing improved the ductility flexural capacity of the UHPC beams. It was also shown that the bending stiffnesses, flexural capacities, and strain responses of the UHPC beams were enhanced upon increasing the reinforcement ratio.

Summary: This paper explores the challenge of accurately modeling Dynamic Strain Aging (DSA) in metals using numerical models. The proposed modification to the Voyiadjis-Abed (VA) model addresses the limitations of current models by introducing an additional microstructures-based parameter to capture the effect of DSA. The modified VA model considers the impurity-dislocation interactions based on the concentration and diffusion kinetics of impurity atoms. Results show successful DSA capture in commercially pure Niobium and Vanadium using physical and microstructural parameters. This study provides a promising approach for accurately modeling DSA activation in bcc metals, enabling future research.
