Structural responses of longitudinally coupled slab tracks (LCSTs) under extreme heat waves (EHWs) and the adaptability track reinforcement measures to cope with EHWs-related issues have been unprecedentedly investigated in this study. A novel finite element model (FEM) assess nonlinear mechanical behaviours LCSTs exposed temperature rise has established. The nonlinearities material constitutional properties, interfacial distribution are taken into account, FEM fully validated by...
Cemented paste backfill (CPB) is a common environmentally friendly mining approach. However, it remains undetermined whether CPB pollutes underground mine water. Tank leaching analysis of mass in distilled water was performed for 120 d, and quality tested situ long-term pollution assessment. Computerized tomography also used to determine the micro-pore structure ion-leaching mechanism. The dissolved Zn2+, Pb2+ As5+ concentrations leachate peaked at 0.56, 0.11 0.066 mg/L, respectively,...
Lithium carbonate (Li2CO3) is a commonly used early strength agent for sulfoaluminate cement based grouting materials. Low concentrations of Li2CO3 (≤30 μmol Li/g in cement) can significantly accelerate the hydration cement. However, effect high (>30 on sulfoaluminate-cement-based materials (SCBMs) unclear. In this study, effects lithium ion (Li+) and (CO32) SCBMs (C4A3S¯–CaSO4–CaO) with different mineral compositions (systems T1 T2) were investigated by calorimetry, X-ray diffraction,...
The grouting materials are new fields where cement clinker (CC) can be replaced by high amounts of steel slag (SS). To develop composite grouts (SSCG) for constructions and repairs in underground engineering, it is necessary to determine optimize the performance SSCG. In this study, SS blast furnace (BFS) contents ternary were all 55–75%. fly ash (FA) 10% 15% quaternary grouts, BFS 20–40%. FA, quinary 5–10%, 25–40% 25–30%. flue gas desulfurization gypsum (FGDG) content was 5%. water-solid...
A single-frequency distributed Bragg Reflector (DBR) fiber laser operating at 1091 nm was demonstrated by using a Yb:YAG crystal-derived silica (YDSF). The YDSF prepared via the molten core (MC) method, with Yb 2 O 3 doping concentration of 5.60 wt.% in core, resulting gain coefficient 1.45 dB/cm nm. Employing 0.8 cm YDSF, we attained maximum output power 145 mW and slope efficiency 31.8%. exhibited an optical signal-to-noise ratio (OSNR) exceeding 71 dB, linewidth ∼34 kHz, stabilized...
