Abstract ：
The development of fiber reinforced asphalt mixture alleviates pavement distress and damage, extending the service life of asphalt pavements; however, the weak fiber/asphalt interface adhesion may limit its wider adoption in practical scenarios. We developed a fiber reinforced asphalt mixture utilizing slag fibers derived from solid waste as a novel solution for waste management. The surface of the slag fibers was modified with silane coupling agents to enhance the interface adhesion between the fiber and the asphalt matrix. Both molecular dynamics simulation and experimental results confirmed the effectiveness of the surface modification, showing increased interfacial compatibility and adhesion. The optimized fiber contents for asphalt mixtures were determined through Marshall tests, indicating that 0.3 wt% of modified short slag fiber or 0.4 wt% of modified long slag fiber yielded the most favorable results. The road performance of asphalt mixture was significantly improved, with increases of > 11.8 % in indirect tensile strength, > 22.5 % in dynamic stability, and > 10.7 % in flexural tensile strength at low temperatures. A great improvement in the stability of the asphalt mixture was achieved under varying temperatures. The robust fiber/asphalt interface allows stress to be easily transferred and enables the asphalt to be tightly absorbed by the fibers, stabilizing the asphalt mixture. After 10 months of service, field evaluations showed minimal deflection and few defects, confirming the practicality and durability of the modified slag fiber reinforced asphalt mixtures. This study offers a feasible and effective way to enhance asphalt pavement performance while addressing solid waste management issues.

Abstract ：
Alkali-activated slag mortars with recycled fine aggregate (AASRMs) have attracted high concern due to their promising properties, low carbon emissions, and solid waste utilization. However, high shrinkage made the AASRMs susceptible to cracking, limiting their application in construction industry. This study intends to use green bamboo cellulose nanofibers (CNFs) as reinforcement to overcome the problem. Two CNFs surface modifications including nano-SiO2 coating and KH590 silane were adopted to improve the dispersibility of CNFs and their compatibility with AASRM matrix. Fourier transform infrared spectroscopy, thermal gravimetric analysis, Zeta potential, and scanning electron microscopy were adopted to characterize the CNF modification. The results showed that adding CNFs evidently improved the mechanical strengths, and reduced the chemical and dry shrinkages of AASRMs. CNF to modifications improved their dispersibility within the matrix, strengthened the fiber/matrix interface bonding, and refined the pore structure of the mortars, enhancing the overall performance of AASRMs. Particularly, the incorporation of 0.3 wt% nano-SiO2- and KH590-modified CNFs into AASRMs enhanced the 28-day flexural strength by 15.5 % and 18.3 %, respectively, compared to the control without CNFs. Moreover, these modifications significantly reduced the 14-day dry shrinkage by 49.9 % and 37.1 %, with nano-SiO2 proving more effective than KH590 in mitigating dry shrinkage. This study offers an effective and green strategy for enhancing the performance of AASRMs by using renewable materials, being beneficial for their large-scale application as sustainable building materials.

Abstract ：
This study introduces an innovative phase-change composite aggregate, integrating paraffin (PA) into waste aerated autoclaved concrete (AAC), enhancing energy efficiency in building temperature regulation. The composite, with a 62 % paraffin volume fraction, showed significant improvements in dry density (71.4 %), compressive strength (34.0 %), and failure strain (25.0 %) over unmodified AAC. It demonstrated a low paraffin leakage rate under 5 %, thermal conductivity of 0.551 W/(m & sdot;K), a phase transition temperature range of 5-45 degrees C, a latent heat of 42.82 J/g, and maintained thermal stability after 300 cycles. Finite element analysis highlighted the impact of porosity and pore size on the compressive strength, while heat transfer simulations underscored the AAC's pore structure's role in convective heat transfer during paraffin melting. Concrete with PA-filled AAC achieved a 28-day compressive strength of 38.2 MPa and a maximum temperature reduction of 15 degrees C during heating, outperforming conventional concrete. This research provides valuable insights into the mechanical and thermal performance of phase-change composites for advanced building materials.

Abstract ：
Traditional polyurethane hot-melt adhesives often fall short in achieving high bonding strength and recyclability, and their dependence on non-renewable resources poses a significant hurdle for sustainable development. In this study, a palm oil-based diethanolamide (POEA) containing a long aliphatic chain was synthesized to develop comb thermoplastic polyurethane hot-melt adhesives (POPUs) with high biobased content, superior adhesion strength, and reusability. The microphase separation structure of POPUs was manipulated through the incorporation of dangling fatty acid chains and hydrogen bonds, resulting in the adhesives with excellent mechanical properties, with an optimum tensile strength of 5.37 MPa and an elongation at break of 282 %. As a hot-melt adhesive, it achieved a maximum lap-shear strength of 7.34 MPa on steel and maintained an average strength of 95 % of its initial value across multiple bonding cycles. Moreover, its lap-shear strengths with wood and glass remained at 6.57 MPa and 3.57 MPa respectively, fully meeting the requirements for interior decoration. Additionally, it was unexpectedly discovered that the adhesives possessed fluorescence characteristics, which can be applied in fields such as cultural relic restoration and anti-counterfeiting.

Abstract ：
Plant oil-based waterborne polyurethanes (WPU) take advantage over traditional solvent-based polyurethanes by using sustainable raw material sources and avoiding VOC emissions. However, the preparation of plant oil-based WPU usually requires long drying times and high energy consumption. Developing plant oil-based WPUs with high solid content and low viscosity emerges as a promising solution for these challenges. In this study, a palm oil-based monomer, POEA-MA, with unevenly distributed carboxyl groups on the side chains was synthesized through thiol-ene click chemistry. Utilizing this unique molecular structure, we successfully developed a palm oil-based WPU with bimodal particle distribution, achieving both high solid content (51%) and low viscosity (277.3 mPa·s). The introduction of 1,6-naphthalenediol as chain extender enhanced the main chain rigidity and increased the hydrogen bond content of the system, allowing the WPU films with tunable tensile properties (tensile strength 1.3‒13.9 MPa, elongation at break 122‒384%) and hardness (4B‒4H). The prepared WPU films demonstrated commendable performance in coating applications, including strong corrosion resistance with a corrosion inhibition rate of 99.56%, outstanding adhesion (5B), high flexibility (Φ 1 mm), impact resistance (1 m), and good solvent resistance. © 2025, The Authors.

Abstract ：
A sustainable and flame-retardant composite facing layers was developed using recycled polyethylene terephthalate (rPET) fiber-mats and renewable soybean oil-based resins. The rPET fiber-mats were surface-treated with a finishing agent composed of paraformaldehyde and dicyandiamide. This finishing agent can interact with the fiber surface both physically and chemically, aiming to enhance composite interfacial adhesion. A flame-retardant soybean oil-based resin, from epoxidized soybean oil, tannic acid, and 2-hydroxyethyl methacrylate phosphate, was used as the matrix. The composites exhibited a limited oxygen index of 28.68 %, with reduced heat release and flue gas emission during combustion. The treatment of rPET fibers contributed to improvements in thermal and mechanical properties of the composites. When used as outer layers, this composite also enhanced both flame retardancy and mechanical performance of the paper honeycomb panels. This study introduces an innovative approach to replacing traditional nonrenewable and flammable facing layers in honeycomb panels with recycled and renewable materials.
