Both micro and nano silica reacts with calcium hydroxide to produce calcium silicate hydrates (C-S-H). Thus the amount of binder is increased, which both increases the strength and reduces the permeability by densifying the matrix of the concrete. As the silica reacts and produces the calcium silicate hydrates, voids and pores within the concrete are filled as the hydrates that are formed bridge the gaps between cement grains and aggregate particles.
