A review on the development and application of graphene based materials for the fabrication of modified asphalt and cement

摘要

As a kind of nano-material, graphene has played a major role in building and construction industries endorsing to its excellent performance. This review classifies graphene based materials according to the number of layers and surface chemical composition and then introduces their physical and chemical characteristics, focusing on the performance improvement effect of graphene based modified asphalt and cement in building materials with focus on their respective construction problems. Relying on physical and chemical modification strategies, and applying various performance analysis indicators, certain directional modification of graphene based materials is proposed to overcome the construction problems and improvement in their performance. In addition, using microscopic characterizations like FT-IR, XRD, SEM, AFM, XPS, the mechanism of action and modification of various graphene based building materials is thoroughly explained.(c) 2021 Elsevier Ltd.
