This project aims to formulate a new mix design for sustainable and resilient infrastructure materials with radically improved material properties and performance, as well as reduced life cycle cost and impact on the environment and societies. The aim of the project is to investigate the effect of dune sand and graphene oxide on mechanical properties and durability of concrete composites including properties and strength relation and alkali-silica reaction in concrete. The optimal mix design will be supported by the understanding of the interaction between graphene oxide, water molecules, dune sand and cement at nanolevel via scanning electron microscopy (SEM) and molecular dynamics simulations.

该项目旨在为可持续和弹性基础设施材料制定新的混合设计，从根本上改善材料性能和性能，并降低生命周期成本和对环境和社会的影响。该项目的目的是研究沙丘砂和氧化石墨烯对混凝土复合材料的力学性能和耐久性的影响，包括性能和强度关系以及混凝土中的碱-硅反应。通过扫描电子显微镜（SEM）和分子动力学模拟，了解纳米级氧化石墨烯、水分子、沙丘砂和水泥之间的相互作用，将为最佳混合设计提供支持。
