Special Issue Information

Dear Colleagues,

The construction industry, which is responsible for around 40% of global carbon emissions, plays a major role in the deterioration of our environment, due to its significant consumption of natural resources and generation of a large amount of waste. Sustainability is an imperative demand for the sector, which is under increasing pressure to diminish its ecological footprint and carbon output. Historically, the choice of building materials was mainly dictated by local building cultures. The 20th century marked a paradigm shift with the use of industrial materials whose physical and economic performances and production efficiency improved.

Many laboratory research works have been carried out around the world to develop building materials that offer renewable sources, low emissions and improved energy efficiency. This Special Issue proposes to study the significant challenges that these materials face in terms of market acceptance and scale-up. For example, economic barriers, such as higher upfront costs and regulatory aspects that prevent the integration of innovative materials into existing building practices, are obstacles that require further study. Case studies are essential to understand the difficulties of implementing sustainable building materials in real projects. By studying the deployment of these materials in real construction projects, valuable information on their performance, durability and environmental impact under real conditions may be obtained. Case studies are indispensable in the field of sustainable construction, serving as in-depth examinations of specific applications of sustainable materials within concrete projects. They provide critical information on material performance, sustainability benefits and practical challenges encountered during implementation.

Limit state analysis provides building designers with a better understanding of fundamental structural resistance and deformation requirements, resulting in an overall material economy and offering clear safety boundary conditions for intelligent structural design. Cold-formed high-strength steel has extensive application prospects in structural engineering due to its excellent mechanical properties and flexible cross-sectional options. However, most existing research focuses on its ultimate strength-related behavior, lacking sufficient investigation into deformation properties. This study aims to comprehensively reveal the continuous variation laws of structural resistance and ductility of cold-formed high-strength CHSs (circular hollow sections) with different cross-sectional selections under axial load. Through reliable finite element analysis, the effects of yield strength (fsy) of cold-formed CHSs, diameter-to-thickness ratio (D/t), and cross-sectional slenderness (λ) on compressive performance in the limit state, including failure mode, axial load-end shortening curve, ultimate-to-yield strength ratio (Nu/Ny), and ductility indicators (displacement ductility coefficient (μ) corresponding to the ascending stage and post-buckling ductility degradation coefficient (R0.85)), were systematically investigated. The results indicate that the dominant failure mode of high-strength CHSs exhibits outward deformation. With an increase of fsy and D/t, the value of Nu/Ny decreases, and the development of multiple compression performance exhibits significant nonlinearity, which indicates that blindly improving material strength may not necessarily be conducive to developing structural compressive performance or achieving efficient and economical design solutions. To better serve the ductile limit design of high-strength CHSs, combined with available experimental data and simulation results, the upper limit of λ is proposed to be 0.22, and the predictive models of μ and R0.85 are established, respectively.

Current international standards (EN 12004; SI 4004) are testing ceramic tile adhesives under post-cure thermal aging. However, the standards omit UV radiation exposure during the fresh-adhesive phase. This research investigated three commercial polymer-modified cement adhesives (C2TE, C2TE-S2, C2T) bonding porcelain stoneware tiles under simulated Eastern Mediterranean and desert conditions. Three commercial adhesives were exposed during the initial (uncured) period to elevated temperature (30 °C), humidity variation (40–65% RH), and UV radiation (295–365 nm, 1.5–2.0 mW/cm2) for 20 min, followed by 28 days of curing. Pull-off testing and scanning electron microscopy, combined with quantitative directionality analysis, were used to characterize the mechanical performance and microstructural degradation. UV exposure of adhesives during tiling working time caused a drop of mean bond strength from 1.77 to 0.26 MPa (85% reduction) compared with 1.77 to 0.64 MPa (36% reduction) under hot-arid conditions. Microstructural analysis of the hardened pull-off adhesives revealed that exposure of the fresh adhesive to UV radiation causes thinning and degradation of the interfacial layer (15–40 µm), leading to a drop in macroscopic strength. In contrast, hot-arid exposure induces adhesive bulk cracking while preserving interface integrity. Fracture surface directionality (goodness parameter), crack density, and delamination percentage together distinguish interface failure from adhesive bulk degradation and provide a forecast of long-term durability. This combined SEM-mechanical approach identified critical gaps in testing protocols and enables evidence-based adhesive selection, as current EN 12004 classifications based solely on mechanical properties prove insufficient.
