Sol-gel synthesis of SiO2 nanosized particles for cement stone structure modifying

Sol-gel synthesis of nanosized particles in the system SiO2-Н2О is considered in order to use them as the potential modifier of cement stone structure. Technological alternatives of introduction of nanomodifier into cement mixture, kinetics of hydration and cement stone hardening modified by synthesized nanoparticles SiO2 are discussed.
