Their microstructure and reactivity are critically influenced by the Al/Si ratio, which in turn varies greatly depending on the original composition of the raw materials. In this study, alumina-silica gels with Al/Si ratios of 0.01–0.91 were synthesized through a two-step carbonation process, aiming at revealing their differences in pozzolanic reactivity. Findings indicate that their pozzolanic reactivity and reaction pathways were governed by chemical composition, Al<img>Si microstructural configuration, and resulting physical properties. An Al/Si ratio of 0.01 resulted in a gel with the highest porosity and specific surface area, as well as the lowest particle size. This gel rapidly formed C–S–H and nearly completed the reaction within 1 d, releasing the highest cumulative heat of 764.9 J/g during its reaction with calcium hydroxide. However, when the Al/Si ratio increased to 0.35, the gel reacted more slowly and exhibited two low-intensity exothermic peaks of 1.7 and 0.6 mW/g that were associated with C–A–S–H and strätlingite formation, respectively. Despite similar compositions and physical properties, gels differed in depolymerization and reaction rates. This was because the incorporation of Na acted as charge-balancing ions when Al tetrahedra replaced some of the Si tetrahedra. Particularly, for the gel with the highest Al/Si ratio of 0.91, its rich Na content greatly accelerated depolymerization. This caused a sharp increase in heat release between 12 and 60 h (218.2 J/g), with strätlingite as the main product.</div></div>","PeriodicalId":266,"journal":{"name":"Cement and Concrete Research","volume":"202 ","pages":"Article 108131"},"PeriodicalIF":13.1,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145908792","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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 investigates the micro-scale creep behavior of cement paste systems incorporating fine limestone filler (LF) as partial cement substitution under coupled relative humidity (RH) and temperature (T) conditions. All mixtures were designed with a stoichiometrically saturated water-to-cement ratio (w/c = 0.40) to promote a high degree of hydration, whereas the water-to-fine (w/f) ratio was adjusted to form dense, UHPC-like matrices. Scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy (EDS) were used to analyze the porosity and microstructure of the cement paste systems. Using an advanced uniaxial creep recovery test on micrometer-sized prismatic specimens (150 × 150 × 300 μm<sup>3</sup>), the viscoelastic response was quantified under seven RH-T combinations. Substituting 30% of cement with LF increased the uniaxial creep modulus by 67% and reduced porosity by 25%. Across all systems, creep deformation increases with higher RH and T levels, and these effects are coupled, each amplifying the influence of the other. Within the investigated range, creep is more sensitive to RH variations than to T, although the inclusion of LF mitigates RH-T-induced creep amplification. Despite the environmental loading, all systems exhibited long-term logarithmic creep kinetics and a consistent recovery index (~ 56%).

Reactive transport modeling is a powerful tool to investigate these mechanisms and has strong potential to provide critical insights into corrosion-related deterioration and thereby contribute to ensuring the durability of traditional and modern low-carbon concretes. Traditional reactive transport models use homogenization techniques that are computationally efficient but overlook the detailed pore structure at the SCI. Our study introduces an approach that leverages high-resolution FIB-SEM nanotomograms to create discretized finite element domains, enabling direct pore-scale reactive transport modeling. We showcase selected examples involving aqueous species relevant to corrosion, including corrosion product precipitation in the interfacial pore network. Simulation results demonstrate that pore structure gives rise to significant local variations in concentrations and precipitate formation, thereby explaining the heterogeneity of corrosion phenomena in cementitious materials. Notably, narrow pores acting as transport bottlenecks caused local aqueous <figure><img></figure> accumulation, promoting <figure><img></figure> precipitation in contrast to more open regions. For comparison, a homogenized model – using independently computed diffusion tortuosity and porosity from 3D pore structures – was implemented. Remarkably, without parameter fitting, this model captured average trends but failed to resolve key localized phenomena like early corrosion product precipitation. We conclude that explicitly modeling pore-scale structures is essential for accurately capturing reactive transport processes at the SCI.
