In the paper the new method of nanosilica addition to cement as an suspension in acetone was tested. It was found that this method helps to avoid the non-uniformly dispersed nanosilica particles in mortar. However, simultaneously it caused the air content in the fresh mortars to be increased. Thus the positive influence of nanosilica on mortar strength is significantly lowered. The application of the proposed method in practise needs the solution of the problem of the increase of air content in the fresh mortar.
