Structural Modification of New Formations in Cement Matrix Using Carbon Nanotube Dispersions and Nanosilica

Complex nanodispersed systems with multi-walled carbon nanotubes and nanodispersed silica have a significant impact on the processes of hydration, setting and hardening of construction composites predetermining their durability. Show that the main effect of the modification of cement matrix in the case of adding complex nanodispersed systems is provided by the directed influence on the processes of hydration and subsequent crystallization of new formations. It is noted that, carbon nanotube dispersion and nanosized silica being added, the binding matrix is structured forming a prefect dense shell from crystalline hydrate new formations on the surface of solid phases that provides strong binding matrix in cement concrete
