High-pressure laminates (HPLs) are widely utilized in interior applications but may have potential as exterior building facade coatings if suitably enhanced for weatherability. Nanoparticle additives are a promising approach to improving the durability and functionality of HPLs. This study aims to evaluate titanium dioxide (TiO 2 ) and silicon dioxide (SiO 2 ) nanoparticles incorporated into HPLs to determine if they impart properties for durable, functional exterior facades. Methods: HPLs were fabricated with 3.75 wt % TiO 2 and SiO 2 nanoparticles in the surface overlay. Industry-standard EN 438 tests characterized the quality, optical properties, and accelerated aging, including UV radiation, weathering, and thermal shocks. Properties were measured before and after aging to compare versus a standard HPL without nanoparticles. Nanoparticles not only increased initial solar reflectance but also caused color changes. After aging tests, nanoparticles did not sufficiently enhance durability compared to the standard HPL. While initial reflectance improved with nanoparticles, overall weatherability did not, indicating a need to optimize fabrication and nanoparticle selection. Although TiO 2 and SiO 2 nanoparticles increased initial HPL reflectance, the feasibility of durable facade coatings was not conclusively demonstrated. Further research should focus on ideal fabrication methods, nanoparticle types and concentrations, and performance in real-world conditions to facilitate adoption in building facade applications.

“…The consequential effect is the creation of a local zone characterized by elevated pressure and temperature within the material, with the primary response coming from the point of load application. This localized response triggers the propagation of an internal shock wave throughout the concrete [10][11][12][13][14]. Furthermore, as the initial compressive wave reflects from the back surfaces of the concrete target, it generates a tensile wave that interacts with subsequent compressive waves.…”

In recent years, the alarming number of terrorist attacks has highlighted the critical need for extensive research aimed at fortifying structures against explosion-induced loads. However, the insufficient energy absorption and brittleness of conventional concrete make it ineffective in withstanding blast loading, encouraging researchers to explore innovative strategies for augmenting the energy dissipation capabilities of construction materials. This study specifically delves into the incorporation of recycled rubber, a sustainable and environmentally friendly solution to the pressing issue of scrap tire disposal. The primary focus of this research revolves around the integration of rubber recycling and steel fibers into concrete, with the ultimate goal of enhancing the dynamic response of reinforced concrete (RC) beams. This novel approach not only contributes to the structural resilience required for resisting blast impacts, but also aligns with eco-friendly practices by reusing recycled rubber. A meticulous numerical investigation was undertaken to comprehensively assess the static and blast response of these augmented beams. The numerical study involved developing finite element (FE) models using ABAQUS version 6.14 for static implicit analysis and LS-DYNA R11 for blast explicit simulations. The ABAQUS model was validated against previous experimental testing for load–displacement and failure patterns. Similarly, the LS-DYNA model was validated for blast pressure in accordance with UFC-3-340 standards and for material response under blast loading, utilizing existing experimental data. The numerical models were designed to accommodate varying weight percentages of rubber, ranging from 5% to 20%, and a consistent 1.0% incorporation of steel fibers. This comprehensive analysis aims to provide valuable insights into the efficacy of these materials in improving the structural integrity and blast resistance of RC beams, thereby contributing to the development of more secure and sustainable construction practices. By reducing the reinforcement ratio in order to meet the minimum code requirements, it became evident that the failures of the rubberized RC beams tended to exhibit ductility on the tension side under static loading. In addition, the increase in the reinforcement ratio correlated with a higher failure load and decreased deflection. Furthermore, the findings indicated an optimal concrete mixture characterized by improved ductility, energy absorption, and blast load capacity, achieved by combining 5–10% rubber with steel fibers.

“…Blast loads can cause significant damage, posing a threat to the safety of occupants if the structural components of a building fail to provide adequate protection [1,2]. In response to this challenge, laminated glass (LG) windows have gained popularity as a major structural component in high-rise buildings, airports, government facilities, and other structures that require a high level of security [3][4][5][6]. Unlike traditional glass windows, LG windows offer enhanced protection during major failure events [7][8][9].…”

“…Various materials can be used to create these interlayers, including polyvinyl butyral (PVB), ionoplast, or thermoplastic polyurethane (TPU). The choice of interlayer material allows for different levels of protection to be achieved [5,[16][17][18]. However, there are other failure modes that can still pose a danger to the surrounding environment when windows are subjected to extreme loading conditions, such as blast loading.…”

Laminated glass (LG) windows significantly enhance building safety due to their ability to retain shattered glass within the interlayer, but their susceptibility to failure under blast loading remains a concern. Compared with simplified models, detailed constitutive modeling is essential to evaluate these complex scenarios, as experimental investigation faces limitations in spatial and temporal resolutions. This study presents a robust model-based simulation approach for predicting the brittle failure response of glass in blast-resistant LG windows. An elasto-damage relation for glass (EDG) was integrated with the finite element model (FEM) to predict the blast response. Validation against shock tube testing results was performed to ensure the reliability of the FEM. Material parameters for the polymeric interlayer were obtained through dynamic experiments, enabling a reasonable representation of its constitutive behavior using the Johnson–Cook (JC) model. Additionally, a numerical parametric study was conducted to investigate how different glass types influence blast resistance performance. Tempered glass stood out for its blast resistance compared with annealed and heat-strengthened glass, displaying superior strength against blast loads. The Rankine-based elasto-damage description provides a more precise representation of the failure response than commonly used approaches. These findings contribute to advancing model-based simulation approaches for designing better blast-resistant LG windows, ensuring safer buildings.
