AbstractThe behavior of cement-based materials is manipulated by chemical and physical
processes at the nanolevel. Therefore, the application of nanomaterials in civil
engineering to develop nano-modified cement-based materials is a promising research.
In recent decades, a large number of researchers have tried to improve the properties
of cement-based materials by employing various nanomaterials and to characterize the
mechanism of nano-strengthening. In this study, the state of the art progress of
nano-modified cement-based materials is systematically reviewed and summarized.
First, this study reviews the basic properties and dispersion methods of
nanomaterials commonly used in cement-based materials, including carbon nanotubes,
carbon nanofibers, graphene, graphene oxide, nano-silica, nano-calcium carbonate,
nano-calcium silicate hydrate, etc. Then the research progress on nano-engineered
cementitious composites is reviewed from the view of accelerating cement hydration,
reinforcing mechanical properties, and improving durability. In addition, the market
and applications of nanomaterials for cement-based materials are briefly discussed,
and the cost is creatively summarized through market survey. Finally, this study also
summarizes the existing problems in current research and provides future perspectives
accordingly.
