1231. Charismatic christianity as primal spirituality? : some observations from SloveniaIgor Jurekovič, 2025, izvirni znanstveni članek Povzetek: The global emergence of Charismatic Christianity ought to be regarded as one of the most consequential phenomena in contemporary history. With estimates reaching as high as 700 million adherents, Charismatics from various denominations have heralded the emergence of Global Christianity. Their considerable popularity has prompted numerous scholarly analyses aimed at elucidating the factors contributing to the emergence of Charismatic Christianity. Social scientists often elaborate on functionalist explanations, suggesting that the popularity of Charismatics can be understood through varying responses to social modernisation. Such explanations, however, frequently neglect the theological innovations inherent to Charismatic Christianity, which garners greater focus from theologians. Among them, Harvey Cox notably asserted that the widespread appeal of Charismatic Christianity can be attributed to its embodiment of experiential primal spirituality. Cox elaborated on three dimensions of Charismatic Christianity as a manifestation of primal spirituality: primal speech, primal piety, and primal hope. The objective of this article is to elucidate Cox’s argument and to examine the advantages of this approach while also offering insights derived from fieldwork conducted among Charismatics in Slovenia. The article posits that Cox’s approach merits appreciation among social scientists, as it identifies unique characteristics of Charismatic spirituality, while also acknowledging its limitations.

1232. Dynamic mechanical analysis of fpu bonded beech wood at various temperaturesMartin Capuder, Boris Azinović, Andreja Pondelak, Paweł Rutkowski, Magdalena Szumera, Matthew Schwarzkopf, Arkadiusz Kwiecień, Klaudia Śliwa-Wieczorek, Jaka Gašper Pečnik, 2025, objavljeni znanstveni prispevek na konferenci Povzetek: This study investigates the dynamic mechanical properties of flexible polyurethane (FPU) adhesives bonded to European beech wood (Fagus sylvatica L.) using Dynamic Mechanical Analysis (DMA) over a range of temperatures and frequencies. Samples included clear beech wood and three-layered composite (beech:FPU:beech). DMA tests were performed using a three-point bending setup at 1 Hz and 10 Hz in the temperature range from -120°C to 140°C. The results demonstrated high thermal stability and strong bonding performance of FPU adhesives on beech wood. Frequency-dependent responses varied among FPU types but resembled the behavior of solid wood at lower temperatures. This confirms the suitability of DMA for evaluating adhesive-wood composite behavior under dynamic conditions. The combination of FPU adhesives and beech wood showed potential for thermally stable and energy-dissipating bonded assemblies.

1233. Natural exposure comparison of timber joints bonded with polyurethane adhesive in two climatic conditionsMartin Capuder, Gary M. Raftery, Weixi Wang, Zubin Karami, Boris Azinović, Andreja Pondelak, Luka Naumovski, Tomaž Pazlar, 2025, objavljeni znanstveni prispevek na konferenci Povzetek: The increased use of engineered wood in the built environment is attracting much attention because of the significant sustainable attributes. The formation of high quality reliable structural adhesive bonds is essential during the manufacture of such products. This research examines and compares the performance of bonded European beech and Radiata pine subject to natural weathering, comparing untreated, preservative treated and mineralized wood. Bonded joints were naturally weathered in Slovenia and New Zealand, respectively. The fracture energy was evaluated through Mode I fracture tests using the double cantilever beam arrangement at various ageing stages. FTIR analysis was conducted to assess chemical changes in the adhesives and wood substrate. The research provides insights into the interactions between ageing, wood species, and adhesive performance, enhancing timber structures sustainability.

1236. Characterization of steel corrosion in alkali-activated mortars using advanced techniquesNina Gartner, Miha Hren, Tadeja Kosec, Andraž Legat, 2025, izvirni znanstveni članek Povzetek: Alkali-activated materials have emerged as a promising substitute for ordinary Portland cement (OPC) in various applications. This study explores the use of different monitoring techniques for assessing the long-term corrosion behavior of steel in alkali-activated mortars, which remains relatively understudied. Three types of alkali-activated mortars (AAMs) were prepared, based on fly ash, slag, or metakaolin as the precursor material. The corrosion of embedded steel was investigated under wetting and drying cycles with chloride-containing solution for up to one year. Two unconventional techniques were used to monitor corrosion: coupled multi-electrode array sensors (CMEA) to measure partial currents, and electrical resistance (ER) sensors to track thickness reduction. The ER sensors enabled evaluation of general corrosion rates over time, while CMEA provided insight into corrosion initiation and its spatiotemporal distribution. In addition, the corrosion damage on the embedded steel and sensors was evaluated using X-ray computed microtomography (microCT). Distinct corrosion patterns were observed depending on the precursor material: severe corrosion in metakaolin-based AAMs, localized pitting in slag-based AAMs, and moderate damage in fly ash-based AAMs. The study demonstrates the complementary value of CMEA and ER sensors and highlights the challenges of characterizing the long-term corrosion processes in these alternative binder systems.

1238. Preliminary assessment of alkali-resistant flax based meshes for reinforcing cementitious compositesJaka Gašper Pečnik, Laetitia Sarah Jennifer Marrot, Marica Mikuljan, Tania Langella, Matthew Schwarzkopf, 2025, izvirni znanstveni članek Povzetek: The production of textile-reinforced concrete (TRC) requires less materials and energy in comparison with conventional concrete reinforced with steel rebars, which draws some solutions towards the production of net zero concrete that the Cement and Concrete Industry sector should reach by 2050. To go one step further, this study investigates the development of flax based meshes as basic components for a reinforcement grid in cementitious materials. Flax strands and hybrid strands (combination of flax strands and glass or basalt rovings) were impregnated with an epoxy resin to form meshes. The physical and mechanical properties of the flax based meshes were assessed and the alkaline resistance of these reinforcing materials was evaluated to determine their durability in a cementitious matrix. At isoweight of reinforcement, the flax-based meshes demonstrated the best performance in terms of specific modulus and specific strength compared to the hybrid meshes. The hybrid meshes from the control batch displayed specific properties in the same range, whether they were constituted of AR-glass or basalt. However, the use of alkali-resistant glass rovings strongly mitigated the degradation of the mechanical properties of the hybrids meshes by making them less affected by the alkaline environment, among all the reinforcement meshes. In contrast, hybrid meshes with basalt experienced an extensive reduction in tensile strength and strain after exposure to alkaline environment, due to the corrosion of the basalt fibres. Pull-out tests revealed maximum bond strengths for the flax based meshes embedded in a high-performance concrete matrix.

1239. Towards harmonized reduction of seismic vulnerability : analyzing regulatory and Incentive frameworks in the Adriatic—Ionian RegionPetra Triller, Angela Santangelo, Giulia Marzani, Maja Kreslin, 2025, izvirni znanstveni članek Povzetek: The Adriatic–Ionian region is seismically very active and poses a major challenge for risk mitigation. Each country has developed laws, standards, and techniques to reduce seismic vulnerability. The ADRISEISMIC project created a database of existing regulatory and incentive frameworks, based on a comprehensive study conducted in six countries. The study covered seismic norms, building regulations, urban planning regulations, incentive frameworks, and post-earthquake planning. A comparative matrix was developed in which key parameters, such as year of issuance, references to EU regulations, level of enforcement, mandatory status, target groups, reference period in relation to earthquake occurrence, and consideration of cultural heritage, were analyzed. The database aims to support a harmonized strategy to reduce seismic vulnerability by promoting measures based on common reference standards. This increases safety, improves the built environment, and minimizes risks to people and nature. Particular attention will be paid to historic urban areas that are both vulnerable and rich in cultural heritage. The collected regulatory and incentive framework will serve as a basis for future research to support the identification of good practices and the formulation of customized roadmaps to apply them to reduce seismic vulnerability.

1240. Multi-scale X-ray techniques for assessing recycled concrete aggregate : from XRPD analysis of leftover cement in recycled aggregates to micro-CT imaging of concrete microstructureA. Bisciotti, Lucia Mancini, Alberto Viani, Vesna Zalar Serjun, Ana Mladenovič, Giuseppe Cruciani, 2025, izvirni znanstveni članek Povzetek: The content of leftover cement paste is a crucial parameter for determining recycled aggregates quality. Various methods assess this, including wet techniques (acid dissolution, chemical degradation, water absorption), physical approaches (freeze-thaw cycles, mechanical shredding, oven-dried density, thermal disaggregation), and spectroscopic or microscopy analyses. However, these methods often lack accuracy, are time-consuming, or depend on operator skill. A novel X-ray Powder Diffraction and Rietveld quantitative phase analysis approach is introduced to improve measurements precision. Results are compared with multi-scale analyses (microscopy, Xray computed tomography, mechanical testing) on recycled aggregate concrete specimens. Findings highlight a strong correlation between leftover cement paste content and key concrete properties, including microstructure, hydration products, and mechanical performance. This study confirms that leftover cement paste content is a decisive factor in recycled concrete aggregate properties, and that the proposed method offers a rapid and reliable approach to control this parameter.
