Popis:	Tubular chrysotile and carbon nanoparticles have been shown to effectively influence the hydration and hardening kinetics, structure formation, and strength of cement systems. Similar in crystal-chemical structure to newly formed hydrated phases, chrysotile nanotubes are the most effective modifier, ensuring a factor of 30 increase in the rate of hydration and hardening processes and a factor of 3 increase in the strength of cement stone. Chemically inert with cement clinker minerals and clinker hydration products, carbon nanotubes ensure a factor of 9 increase in the rate of hydration and hardening processes and a factor of 1.5 increase in strength.
