Summary: Basalt fiber (BF) has gained significant attention in recent years for its advantageous mechanical properties and cost-effectiveness in basalt fiber reinforced concrete (BFRC). This study investigates the performance of BFRC after cryogenic freeze-thaw cycles, examining the effects of fiber volume fraction, temperature gradient, and freeze-thaw cycles on various strengths and analyzing the damage mechanism through scanning electron microscopy (SEM). The results reveal that BFRC reaches peak compressive strength at a fiber fraction of 0.1% during freezing and thawing cycles from room temperature to -80 degrees C. The addition of basalt fibers reduces microstructural damage and improves plastic degradation characteristics. Furthermore, the optimal fiber content for compressive strength increases with decreasing minimum temperature of the cryogenic freeze-thaw cycle while splitting tensile strength and flexural strength improve with increasing fiber content in the cryogenic freeze-thaw environment.

Summary: This study investigates the effects of three design variables, namely the replacement rate of recycled aggregate, the content of steel fiber, and the loading rate, on the stress-strain relationship and mechanical properties of steel fiber reinforced recycled concrete (SF-R-RAC) under cyclic loading. The failure mode and cyclic stress-strain curve law of SF-R-RAC are observed and summarized. The influence of different design variables on stiffness degradation and energy dissipation is described, while a piecewise function is used to fit the envelope of the cyclic stress-strain curve. This research provides a theoretical basis and experimental reference for further study of SF-R-RAC.

Summary: The study introduced a novel 3D-printing ultra-high performance fibre-reinforced concrete (3DP-UHPFRC) and evaluated the effect of fibre content, type, and printing direction on its mechanical properties. The results showed that 3DP-UHPFRC with 1 vol% 6 mm steel fibre had higher flexural strength in the Z-direction compared to previous studies, and the failures could be either ductile or brittle in different directions, allowing for flexible adjustment of printing mode based on engineering requirements. The compressive elastic modulus was found to be anisotropic, while there was little difference in the tensile elastic modulus in each direction.

Summary: This paper presents experimental research on the mechanical characteristics of concrete reinforced with natural cellulosic fibers. The study found that the tensile and compressive strength of concrete increased with the addition of natural fibers, up to a certain proportion. However, a further increase in fiber loading resulted in a deterioration of the mechanical properties. Using jute and sisal fibers, a significant improvement in strength was observed by adding 2% fibers to the concrete mix. Bending strength increased up to a certain fiber loading, but decreased beyond that due to cracks at the fiber-concrete interface. The impact performance gradually improved with the addition of natural fibers up to 2%. The water absorption capacity of the reinforced concrete decreased, but increased with the loading percent of fibers. The study concludes that natural fiber reinforced concrete can be a sustainable construction material for future use in pavements and flooring slabs.

Summary: This study investigated the bond performance of steel bars and steel fiber recycled concrete by designing different mix proportions and conducting pull-out tests. The results showed that the bond strength between steel bars and steel fiber recycled concrete decreased with increasing replacement rate of recycled aggregates. However, the bond strength increased with higher mixing amount of steel fibers. Additionally, the slip value of the specimen under peak load increased with higher mixing amount of steel fibers.

Summary: This study examines the effectiveness of fibers (polypropylene and steel) in different concrete pavement mixtures and the impact of their varying quantities on the performance of concrete pavements through extensive experimental and numerical analysis. The results show that fiber reinforced concrete mixtures have similar strength, stiffness, absorption, and porosity, but higher abrasion resistance and post cracking performances. Reductions in required thickness values were observed for polypropylene and steel fiber reinforced mixtures. Changes in pavement material costs and CO2 emissions were also observed for fiber reinforced concrete mixtures. The observations are dependent on the type and amount of fibers and properties of concrete matrices.

Summary: The aim of this research is to investigate the impact of microsilica and polypropylene fibers (PF) on the mechanical characteristics of ultra-high performance geopolymer concrete (UHP-GPC). The experimental results showed that the addition of 15% microsilica significantly degraded the mechanical characteristics, but further addition of microsilica enhanced the characteristics. Moreover, introducing 2.75% PF effectively minimized the decrease in characteristics when 15% microsilica was used, and PF contributed significantly to the mechanical characteristics of UHP-GPC.

Summary: The study investigated the mechanical properties of polypropylene fiber all-coral seawater concrete under triaxial compression, finding that the best deformation properties were achieved with the addition of 3 kg center dot m(-3) of polypropylene fiber. The correct amount of polypropylene fibers significantly enhanced the strength and ductility of the material, improving its brittle characteristics. Additionally, the confining pressure value and polypropylene fiber coupling effect delayed the appearance of initial damage, slowed damage development, and reduced damage severity during triaxial compression.

Summary: This paper discusses the deterioration of fracture properties of rubber powder modified polypropylene fiber concrete (RPFC) after elevated temperatures. The results show that incorporating rubber powder into polypropylene fiber concrete can delay the crack propagation process, improve the deformation ability and make the fracture path more tortuous. With the increase of rubber powder content and ambient temperature, the fracture toughness and energy of RPFC exhibit different trends. AE analysis further indicates that the growth rate of accumulate counts decrease significantly with the rubber powder content in RPFC, suggesting a slowed down rate of damage development.

Summary: Steel-fiber-reinforced concrete (SFRC) exhibits different internal micro-structure and damage characteristics due to the varying content and random distribution of steel fibers. This study investigated the influence of steel fiber volume fractions on the splitting-tensile strength of concrete and analyzed the microscopic failure mechanism of SFRC. Results showed that the addition of steel fibers improved the splitting-tensile strength of concrete, with a maximum value observed at a volume fraction of 1.5%. The failure process involved four stages, with tensile failure dominating and a partial shear failure.

Summary: In this study, nano-SiO2 and basalt fiber were used to improve the quality of recycled aggregate concrete. The effects of different contents and lengths of basalt fiber on the mechanical properties of the concrete were analyzed, as well as the micro-composite effect between nano-SiO2 and basalt fiber. The study found that the optimum modified concentration of nano-SiO2 was 2%, and the optimum length and content of basalt fiber were 12 mm and 0.2%, respectively. The addition of basalt fiber significantly increased the compressive strength, splitting tensile strength, and flexural strength of the concrete.
