The use of nanosized particles in P

The use of nanosized particles in Portland cement-based materials affects the microstructure and the properties of the cementitious materials that are responsible for increasing the liquid phase viscosity, reducing segregation, increasing workability, filling the voids between the cement grains (filler effect)14 and accelerating the hydration reactions.15 These processes favor the formation of small calcium hydroxide crystals and hydrated calcium silicate clusters (C-S-H, in accordance with notation used in the chemistry of cement: C = CaO; S = SiO2; H = H2O).
