Nanomaterials like nano sio 2, nc, nanotubes, and go enhance hydration kinetics, accelerating cement hydration and improving mechanical properties. these nanomaterials occupy pores, act as nucleation sites, and exhibit pozzolanic reactivity, leading to denser microstructures and increased strength. The results showed that nano c s h seed crystal can promote the early hydration of cement, and the hydration promotion effect decreased with the hydration time and increased with the content of nano c s h seed crystal. The experimental results indicate that the addition of nano limestone and nano silica accelerated cement early hydration, the maximum heat flow increased, whereas the time to reach the heat flow peaks decreased. Abstract many studies have focused on the feasibility of using nanoparticles including nanoalumina (na), in cement composites and reported some positive effects on the properties of concrete. however, there are still uncertainties about the effects of na addition on cement hydration.
