Abstract

The physical-mechanical properties of concrete with nanosilica were experimentally studied. Nanosilica in powder form was used as a partial replacement of cement at dosage of 3 and 6 wt.%. The experimental results show that the compressive strengths of concretes with nanosilica particles were all higher than those of reference concretes at ages 1, 7, 28 and 90 days. Also, at age of 28 days flexural strength, dynamic modulus of elasticity and apparent density have been increased, while water absorption has been decreased.
