Alcoholysis technology can degrade waste PU into polyols for recycling, and the by-product (BPF) can be used as asphalt extender to produce BPF-asphalt while maintaining good performance. Based on the previous research, this study focuses on the interaction between BPF and asphalt at a molecular scale. Two types of BPF (BPF-A and BPF-B) were selected, and the molecular models were established based on their chemical compositions analyzed by nuclear magnetic resonance, which revealed their primary constituents as propylene oxide (PO), ethylene oxide (EO), and diamino diphenylmethane (MDA). The interaction energy between each component of BPF with each component of asphalt is negative, with polyether (EO/PO) showing the strongest interaction due to hydrogen bonding, followed by aromatic amine through hydrogen bonds and π-π stacking, proving that there is good compatibility between BPF and asphalt molecules. In addition, the tensile model was established to simulate the cracking behavior at different loading rates and verify the results of tensile ductility tests. The results show that the rapid tensile of molecular chains at high loading rates inhibits viscous relaxation, thereby improving the instantaneous load capacity. The excessively low loading rates may lead to the loss of energy dissipation efficiency due to excessive relaxation of the molecular structure. BPF-A, which is richer in polar EO groups, forms stronger hydrogen bonds with asphalt, yielding higher peak traction under rapid loading. Conversely, BPF-B’s rigid PO-dominated structure enables superior energy absorption and peak traction at low loading rates due to delayed molecular relaxation.</p></div>","PeriodicalId":691,"journal":{"name":"Materials and Structures","volume":"58 6","pages":""},"PeriodicalIF":3.9,"publicationDate":"2025-08-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144832160","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Non-destructive IRT were performed on disk-shaped specimens of hot mix asphalt (HMA) at − 20 °C and + 23 °C to determine their resonance frequencies, which are critical for their viscoelastic characterization. Both an analytical method and a numerical back-calculation method were utilized to determine the complex modulus (dynamic modulus and phase angle) of the specimens based on IRT data. Both analytical and numerical methods yielded consistent dynamic modulus values. At − 20 °C, they ranged from 25,000 to 40,000 MPa. At room temperature, values were between 10,000 and 20,000 MPa. However, the two methods differed in their phase angle estimates, especially at higher temperatures, with discrepancies ranging from − 6° to + 3°. The study identifies limitations in current numerical back-calculation techniques, particularly regarding damping estimation, and suggests improvements in optimization procedures. The results also highlight that air void content significantly affects HMA stiffness (about 1000 MPa per % air void content), with higher air voids reducing the dynamic modulus, particularly at lower temperatures.

The spatial distribution of steel fibers, governed by the rheological properties of the mortar, exerts a critical influence on the toughening efficiency and crack resistance of SFRC. In this study, seven types of cement mortars with various rheological properties and corresponding SFRCs were prepared and investigated to the effect of mortar rheology on fiber dispersion and spatial distribution. Quantitative correlations were established between the rheological properties and two-dimensional (2D) fiber dispersion indicators, including the fiber distribution coefficient (<i>α</i>), orientation coefficient (<i>φ</i>), and effective utilization rate (<i>η</i>). Additionally, the effect of these indicators on the mechanical performance of SFRC was quantified. The spatial distribution characteristics were subsequently analyzed using X-ray computed tomography (CT) with three-dimensional (3D) reconstruction of steel fibers. The results indicated that both <i>φ</i> and <i>η</i> attained peak values when the mortar’s yield stress ranged between 40.00 and 60.00 MPa and its plastic viscosity was within 0.40 to 0.60 Pa·s. Optimal fiber orientation coefficient (<i>α</i> = 0.90–0.92) and effective utilization rate (<i>φ</i> = 0.70–0.75) can enhance the compressive strength of SFRC to 33.6 MPa. The probability distributions of fiber distance r and angle θ followed normal distributions, while the angle φ conformed to an exponential distribution. This study contributes to optimizing the SFRC mixture design and enhancing fiber utilization, while the proposed fiber spatial distribution models serve as input for mesomechanical modeling of SFRC, thereby enabling the simulation of its anisotropic behavior governed by rheological properties.</p></div>","PeriodicalId":691,"journal":{"name":"Materials and Structures","volume":"58 6","pages":""},"PeriodicalIF":3.9,"publicationDate":"2025-08-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144814408","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study addresses these limitations by investigating the seismic behavior of rammed earth walls enhanced with different structural constraints and material compositions. Nine test models, all of the same size but produced using distinct construction techniques and material mixes (Mixes 1 and 2), were categorized into three series: unconstrained rammed earth walls (W1-1 to W1-3), reinforced concrete frame-constrained walls (W2-1 to W2-3), and steel frame-constrained walls (W3-1 to W3-3). Low-cycle repeated loading tests were conducted to evaluate the structural responses. The results showed that the reinforced concrete and steel frame constraints significantly improved the load-bearing capacity and deformation resistance of the walls. The unconstrained walls exhibited a minimum cracking load and ultimate load of 245 and 382 kN, respectively. In contrast, the reinforced concrete frame-constrained walls achieved superior performance, with a minimum cracking load and ultimate load of 400 and 597 kN, respectively. The steel frame-constrained walls displayed intermediate results, with a minimum cracking load of 338 kN and an ultimate load of 554 kN. Additionally, the specimens using Mix 2 (W1-3, W2-3, and W3-3) demonstrated the highest energy dissipation.

The use of natural lignocellulosic fibers stands out over synthetic fibers because they are renewable and offer desirable technological properties such as high tensile strength and low specific gravity. These fibers also have a lower cost than other reinforcements, such as synthetic fibers. In this context, the objective of this study was to investigate the physical and mechanical properties of fibers extracted from the pineapple leaves, a waste widely generated in producing areas. The fibers were characterized in their natural form and after treatment by immersion in a 5% alkaline solution/1 h (mercerization). Parameters such as average diameter, water absorption, density, tensile strength, deformation and modulus of elasticity were obtained. Several analyses such as XRD, FTIR, DSC and SEM were performed to compare treated and untreated fibers for a more efficient application in geopolymers. A thermal behavior study, with 28 days of exposure at 60 °C, was carried out to analyze the possibility of thermal curing in a possible application in geopolymers. The treated fibers obtained a considerably superior performance in all properties analyzed. In this context, geopolymer composites were prepared using treated fibers to evaluate the fresh and hardened state of the mortars, obtaining the consistency index, flexural strength and compression. The composites had the addition limited by the workability of 3% and reached approximately 17 MPa of mechanical resistance to compression, with the addition of fibers being beneficial to the context studied.
