چکیده:

Keywords: Until now silica fume has been considered as one of the best pozzolanic materials in concrete technology. This study investigates the effects of nano silica and silica fume on various durability properties of self consolidating mortars (SCMOs). Tests include fresh properties workability, workability, compressive strength, water permeability, capillary water absorption, rapid chloride permeability and surface electrical resistivity. Thirty mortar mixture, In addition, results show that nano silica has enhanced compressive strength and durability of SCMOs and reduced Chloride permeability.
