Amorphous nano-silica (nS) particles (0โ2.5wt%) by cement were incorporated in cement pastes and mortars, and their effect on the fresh state behaviour was analysed. Rheological tests showed that after 75min from the mixing start, the mortar having 2.5wt% nS shows insufficient flowability to allow i
