偏高岭土-水硬石灰砂浆是一种修复性材料,主要应用于古建筑修复领域。 Abstract: Metakaolin-hydraulic lime mortar is a repairable material, which is mainly used in the field of ancient building restoration. Graphene is a two-dimensional crystal composed of carbon atoms with only one layer of atomic thickness, and has good toughness. Graphene-modified metakaolin-hydraulic lime mortar was used to study the changes in mortar properties and reaction products. The results show that the addition of graphene can effectively improve the mechanical properties and volume stability of metakaolin-hydraulic lime, and the microstructure gradually becomes dense, and the inter-particle voids are reduced.
