چکیده انگلیسی
This study evaluates the effect of addition of nano silica, Cu0.5Zn0.5Fe2O4 (Cu-Zn ferrite) and NiFe2O4 (Ni ferrite) on the compressive strength, splitting tensile strength, flexural strength and modulus of elasticity of concrete. Nano-silica (NS), Cu-Zn ferrite and Ni ferrite, was added in five percentages (1%, 2%, 3%, 4% and 5%) of weight of cementitious materials (cement and SF). We use two types of coarse aggregate (dolomite and granite) and the study of the effect on the mechanical properties of concrete containing nano-materials. Results indicated that the optimum dose of nano-silica was 3% by weight and the optimum dose of Ni ferrite and Cu-Zn ferrite was 2% by weight. The samples of concrete-containing nano-silica gave better results from samples of concrete-containing nano ferrite and the approximate rate of about 10%. Also, the samples of concrete containing granite gave better results than similar-containing dolomite and the approximate rate of about 10%.
