Summary: This study investigated the effects of different aggregate combinations on the long-term mechanical and shrinkage properties of fully recycled aggregate concrete (FRAC). It was found that using fully recycled aggregate combinations had negative effects on the concrete properties, and the effect caused by fully recycled aggregate combination was higher than the sum of the effects caused by fully recycled coarse aggregate and fully recycled fine aggregate combination. Additionally, the study examined the impact of recycled powder (RP) on FRAC properties and found that RP content affected the mechanical properties and shrinkage strain of FRAC.

Summary: This study proposed a new bio-inspired hierarchical circular honeycomb (BHCH) with excellent energy absorption capacity. The experimental results showed that BHCH outperformed the conventional circular honeycomb in terms of energy absorption and had significantly higher relative stiffness, strength, and energy absorption than other cellular structures. The theoretical model analysis further demonstrated the enhanced energy absorption mechanism of BHCH.

Summary: The study highlights the significant role of long-term prestressed loss and mechanical property evolution in steel/concrete structures strengthened with prestressed CFRP plates. A new prestressed tension device and anchorage system were proposed to enhance the reliability and load-bearing capacity of CFRP plates. Exposure of CFRP plates to elevated temperatures, distilled water, and sustained loading resulted in gradual degradation of tensile strength.

Summary: This study investigates the effects of different proportions of almond skin powder as reinforcement in polylactic acid (PLA) matrix on the mechanical performance, thermal stability, and rheological property of the feedstock filaments. Results showed that 2.5 wt% almond skin powder effectively strengthens the filaments, but increasing the proportion to 5 wt% significantly reduces the mechanical strength and melt flow index of the PLA matrix.

Summary: Aminated lignin was prepared using ultrasonic treatment at different frequencies, and the best adsorption capacity and regenerability for As(V) were found at a frequency of 32 kHz. The Langmuir model and pseudo-first-order/pseudo-second-order kinetics models were used to describe the adsorption process, indicating it is a physical/chemical process. This study provides a new idea for the development of lignin-based materials and offers an innovative approach for highly effective removal of As(V) from wastewater.
