{"title":"Durability assessment of Arucas Ignimbrite as a natural building stone under freeze–thaw and thermal shock ageing","authors":"José A. Valido, Patricia Vazquez, José M. Cáceres, Luís Sousa","doi":"10.1016/j.jobe.2026.117246","DOIUrl":"https://doi.org/10.1016/j.jobe.2026.117246","url":null,"abstract":"Arucas ignimbrite, commercially known as <ce:italic>Lomo Tomás de León</ce:italic>, is a volcanic building stone widely used in the Canary Islands and exported internationally. This study evaluates its durability after 60 freeze–thaw and 60 thermal shock cycles using apparent density, open porosity, water absorption, ultrasound propagation velocity, mercury intrusion porosimetry, fluorescein-impregnated thin sections, uniaxial compressive strength and colour variation. Both ageing procedures produced descriptive changes, but with different intensity and evolution. Although pairwise changes in physical properties did not reach statistical significance after Bonferroni correction, freeze–thaw ageing showed larger changes in mean open porosity (+20.5%) and water absorption (+5.8%), together with ultrasound propagation velocity reductions of up to 12.6% and compressive-strength losses of approximately 21–22%. Thermal shock produced more moderate and partly non-monotonic changes in pore-related properties, with strength losses of 8.9–18.4% and ultrasound propagation velocity reductions of up to 13.5%. Apparent density remained virtually unchanged under both treatments. Microstructural observations suggested that deterioration may have been influenced by the anisotropic flow fabric, large feldspar crystals, porous glassy matrix and pore-size distribution. The porous matrix may have partially accommodated thermally induced strains, whereas freeze–thaw ageing was associated with a more developed fracture network, consistent with opening and propagation of pre-existing discontinuities and possible formation of new microcracks. Colour changes remained moderate and were mainly related to surface lightness. Overall, the results show greater susceptibility to freeze–thaw ageing and support durability assessment of volcanic-stone building elements.","PeriodicalId":15064,"journal":{"name":"Journal of building engineering","volume":"1 1","pages":""},"PeriodicalIF":6.4,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148883812","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, carbon retrofitting remains under-adopted in developing economies such as Nigeria, where financial, technical and institutional barriers constrain uptake and limited research explains how these factors jointly shape professionals’ adoption intentions. This study investigates the determinants of carbon retrofitting adoption intention among built environment professionals in Lagos State, Nigeria. Drawing on four complementary theoretical frameworks - the Theory of Planned Behavior (TPB), Diffusion of Innovations (DOI), Institutional Theory and the Unified Theory of Acceptance and Use of Technology (UTAUT) - the study examines how cognitive evaluations, technological attributes, normative influences and institutional pressures shape professionals’ willingness to implement carbon-oriented retrofit measures. A hybrid analytical design integrating Partial Least Squares Structural Equation Modelling (PLS-SEM) and fuzzy-set Qualitative Comparative Analysis (fsQCA) was applied. Survey data from 110 professionals were analyzed to estimate linear effects and uncover multiple causal pathways that lead to high adoption intention. PLS-SEM captured the direct influence of environmental awareness, cost perceptions, regulatory support, technical feasibility, peer influence, trust in providers and performance expectations, while fsQCA identified alternative combinations of these factors that jointly foster strong adoption intentions. All seven hypotheses (H1–H7) were supported, with cost savings and expected performance benefits demonstrating the strongest predictive effects. The results underscore the need for targeted capacity-building initiatives, credible provider networks, financial incentives and profession-driven advocacy to accelerate retrofit uptake. The study provides one of the first multi-theory, dual-method insights into carbon retrofitting adoption in Sub-Saharan Africa.","PeriodicalId":15064,"journal":{"name":"Journal of building engineering","volume":"52 6 1","pages":""},"PeriodicalIF":6.4,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148883817","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
