Summary: The production of ductile and environmentally-friendly concrete becomes possible by using recycled fibers and pozzolanic materials. Purification of recycled steel fibers can improve the engineering properties of the concrete, especially the imperviousness and flexural performance. However, it negatively affects the ultrasonic pulse velocity and compressive strength.

Summary: Along with the increase in global vehicle sales, waste tires are becoming an increasingly serious problem. Reusing these waste materials instead of disposing them is crucial for preventing environmental pollution and creating new low-cost products. This study investigates the effect of recycled steel wires from waste tires on the properties of traditional reinforced-concrete beams. The results show that increasing fiber content effectively enhances the compressive and tensile strength of concrete.

Summary: This paper presents a study on the flexural behavior of reinforced concrete beams reinforced with industrial recycled steel-wire mesh high-performance mortar. The results show that the weaving of steel wires into a mesh and the use of rebar-planting anchorage measures effectively enhance the load-carrying capacity and inhibit crack development. Finite element analysis confirms the effectiveness of this strengthening method.

Summary: Construction waste and waste fabric are major types of solid waste that cause landfill issues and environmental pollution. This study presents an innovative solution to transform waste concrete and waste polyester fabric into recycled foamed concrete (RFC), which has excellent economic and environmental benefits. The research findings demonstrate that the addition of recycled powder can improve the compressive strength of foam concrete, while PET fiber reinforcement enhances durability. Recycled PET fiber shows better enhancement effects compared to PET fiber.

Summary: Recycled aggregate concrete (RAC) has become a good alternative to natural aggregate concrete (NAC) due to increased sustainability focus, but has drawbacks such as lower strength and higher water absorption compared to NAC. Adding fibers to RAC can improve mechanical properties and durability, with steel fibers showing the best enhancement in mechanical properties. Basalt fibers offer better sustainability. This study aims to inform further research on using fibers to enhance RAC properties.

Summary: This study assessed the compressive performance of sisal fiber-reinforced recycled aggregate concrete (SFRAC) composite confined with jute fiber-reinforced polymer (JFRP) tube. It was found that the prefabricated JFRP tube significantly enhanced the compressive strength and deformation ability of the composite. The sisal fiber reinforcement improved the integrity of the concrete and reduced crack propagation.

Summary: This study investigated the mechanical, flexural post-cracking, and torsional behaviors of recycled steel fiber-reinforced concrete (RSFRC) incorporating steel fibers obtained from recycling of waste tires. The results showed that the inclusion of recycled steel fibers improved the post-cracking flexural behavior, energy absorption, ductility, and residual flexural strength of RSFRC. Additionally, RSFRCs exhibited improved post-elastic torsional behaviors in terms of torsional capacity and ductility.

Summary: This study investigated the seismic performance of steel fiber-reinforced recycled concrete-filled steel tube (SRACFST) columns. The addition of steel fiber effectively compensated for the defects of recycled aggregate concrete (RAC) and improved lateral bearing capacity, ductility, and energy dissipation. However, higher axial compression ratio and concrete strength weakened the deformation capacity, ductility, stiffness stability, and strength stability. The study recommended the use of the AIJ-2001 code to calculate the compression bending bearing capacity of SRACFST columns and proposed a fiber modelling (FM) method for further elastoplastic analysis.

Summary: The experimental study evaluated the ductility of reinforced concrete beams with hybrid FRP-steel bars. Results showed that the position of reinforcement had a significant impact on beams with lower hybrid reinforcement ratios. Beams with hybrid reinforcement had higher flexural capacity and increased ductility compared to beams with conventional steel bars, but ductility decreased as the hybrid reinforcement ratio increased. The numerical model developed in the study accurately predicted the flexural behavior of beams with hybrid reinforcement. The study proposed using neutral axis angle and displacement index to evaluate ductility of cross-sections with hybrid reinforcement.

Summary: The use of recycled steel fibers as an alternative to industrial steel fibers for concrete reinforcement was assessed in terms of technical and environmental impact. Numerical simulations accurately fitted experimental results to derive the tensile stress-crack width relationships of RSFRC and ISFRC. It was demonstrated that the environmental impact of RSFRC production is reduced compared to ISFRC with the same concrete strength class.
