Forthcoming articles have been peer-reviewed and accepted for publication but are pending final changes, are not yet published and may not appear here in their final order of publication until they are assigned to issues. Therefore, the content conforms to our standards but the presentation (e.g. typesetting and proof-reading) is not necessarily up to the Inderscience standard. Additionally, titles, authors, abstracts and keywords may change before publication. Articles will not be published until the final proofs are validated by their authors.

Forthcoming articles must be purchased for the purposes of research, teaching and private study only. These articles can be cited using the expression "in press". For example: Smith, J. (in press). Article Title. Journal Title.

  • Effect of nano-silica on properties of aqueous epoxy repair materials   Order a copy of this article

    Abstract: The commonly used tunnel crack repair materials tend to experience performance degradation under erosive environments. To address this issue, this study introduces Nano-silicon (NS) into a waterborne epoxy system composed of epoxy resin and polyurethane, and combines it with cement to develop a high-performance waterborne epoxy repair material. The mechanical properties of materials with varying NS content-including compressive strength, flexural strength, compressive-to-flexural strength ratio, bonding strength, and durability under chloride ion erosion-were tested. Concrete substrate repair experiments, along with SEM and EDS analyses, were also conducted. The results show that an appropriate NS content (0.5%-1%) can reduce porosity, promote early hydration, and enhance early strength, significantly improving the mechanical performance and durability of the material. The developed material effectively meets the requirements for tunnel crack repair. This study provides both theoretical support and experimental evidence for the performance enhancement and practical application of waterborne epoxy-based repair materials.
