The effects of addition of amorphous nanosilica particles to three grades of cement mortars P ortland pozzolana cement 33, ordinary P ortland cement 43, and 53 are investigated. The nanosilica particles are used as a partial replacement of cement by 0.25, 0.50, 0.75, 1.00, and 1.25 wt.%. The tests of cement mortars are carried out in water for 3rd, 14th, 28th, and 90th day. Addition of nanosilica reduces the setting time and in turn increases the compressive strength and saturated water absorption, and its digestion of calcium hydroxide crystals leads to a decrease in the size of crystals accumulated at the interface.
