title: Enhancement of mechanical and microstructural properties of high-volume slag cement paste using treated cedar wood fly ash

description: High-volume slag cement (HVSC) is a sustainable alternative to traditional cement but exhibits low early-age strength. This study explores the use of treated cedar wood fly ash (CWFA) as an additive in HVSC paste, focusing on fresh, mechanical, and microstructural properties. Paste mixtures were prepared using varying proportions of ground granulated blast-furnace slag (GGBFS) and cement at ratios of 30:70, 50:50, and 70:30, with CWFA added at replacement levels of 10%, 20%, and 30% by weight of the binder. The results indicated that incorporating 10% and 20% CWFA increased heat evolution within the first 48 h by 25.5% to 60.5% compared to mixtures without CWFA. This accelerated hydration significantly improved early-age compressive strength, with enhancements ranging from 50% to 165%, particularly in mixtures containing 50% and 70% GGBFS. This research provides a solution to the early-age strength limitations of HVSC systems and contributes to the development of green cementitious materials.HighlightsHigh-volume slag cement (HVSC) and cedar wood fly ash (CWFA) were used to produce the modified paste.The incorporation of CWFA enhances the hydration reaction, resulting in an increased heat of hydration.Adding CWFA significantly enhances the early-age strength of the HVSC paste.Using CWFA improves the microstructure of the HVSC paste.Using a high volume of GGBFS along with CWFA reduces CO2 emissions.

title: Imaging the mantle transition zone beneath East Asia using teleseismic receiver functions: implications for thermal and compositional heterogeneities

description: The mantle transition zone (MTZ) plays a critical role in regulating material flux and mixing between the upper and lower mantle. Variations in MTZ structure are closely associated with mantle temperature and compositional heterogeneities, making it essential to constrain these variations to better understand mantle dynamics. To investigate the MTZ structure beneath East Asia, where the stagnant Pacific slab and intraplate volcanism provide a unique geodynamic setting, we examined over 40,000 <i>P</i>-to-<i>S</i> converted waves from 18 seismic networks in Korea, China, and Japan. Common conversion point (CCP) stacking revealed significant regional variations in MTZ discontinuities and heterogeneous lateral variations in converted wave amplitudes. The average depths of the 410-km (d410) and 660-km (d660) discontinuities were 416 ± 10 km and 668 ± 11 km, respectively, yielding a mean MTZ thickness of 252 ± 14 km with notable localized deviations. CCP-stacked profiles at 0.2 Hz and 0.5 Hz highlighted the structural complexities, revealing evidence for multi-layered MTZ boundaries. Converted wave amplitudes exhibited lateral variations on scales of 200 km and larger; however, these variations in amplitudes did not correlate with the variations in discontinuity depths. A pronounced depression of the d660 beneath the Korean Peninsula and northeastern China likely reflects the influence of the cold, stagnant, and near-horizontal Pacific slab. The accompanying d410 depression beneath the Korean Peninsula suggests compositional heterogeneity, possibly linked to water and carbon enrichment. Near-normal MTZ discontinuity structures beneath the Ulleung and Jeju intraplate volcanoes indicate limited influence from the stagnant Pacific slab, potentially due to a slab tear or a localized thermal anomaly near the base of the MTZ. Mantle upwelling through such a tear is likely hydrous rather than purely thermal, consistent with the near-normal d410. These results demonstrate that regional MTZ anomalies reflect interactions among mantle upwelling, slab-derived heterogeneities, and volatile-rich components.

title: Development of eco-hydrophobic composite concrete: a multi-scale investigation of strength, durability, and sustainability metrics

description: Hydrophobic concretes using silane, siloxane, or fatty acid-based admixtures provide water repellency but often impair hydration efficiency and mechanical strength. Conversely, pozzolanic blends with SCMs enhance microstructural densification yet remain hydrophilic, creating a critical gap for multifunctional admixtures that deliver both hydrophobicity and pozzolanic reactivity. This study investigates M40 grade concrete incorporating Symbio-Pozzolanic Composite Hydrophobic Powder (SPCHP), synthesized from fly ash, silica fume, metakaolin, and zinc stearate, as a fine aggregate replacement (10–30%). The optimum mix (SPCHP20) achieved a 28-day compressive strength of 45.2 MPa, only 2.1% below control, while reducing water absorption and sorptivity by 75% and chloride permeability by 56.6%. Acid and sulfate resistance improved significantly. Microstructural analysis confirmed dense C–S–H gels (Ca/Si = 1.71) with a water contact angle of 116.3°. Life-cycle assessment showed 18.5% lower global warming and 21.3% lower acidification potential, validating SPCHP’s dual hydrophobic–pozzolanic functionality.

title: BETA-FOR_SP9_Spiders_2022/2023

description: This dataset includes records of spider species collected using pitfall traps across the 234 BETA-FOR patches. Two traps were installed 7 meters from the center of each patch, positioned in the northwest and southeast. Traps were emptied at the end of May, June, and July.

Sampling was conducted in 2022 for 90 patches in the University Forest and 90 patches in the Bavarian Forest. In 2023, 54 patches located in Saarland, Hunsrück, and Lübeck were sampled.

All collected spider samples were identified by Jean-Léonard Stör.
