In this paper, the effect of using natural zeolite as a supplementary cementitious material and micro-nano bubble as a substitute for concrete mixture water has been evaluated on the mechanical properties and durability of concrete. The evaluated parameters for properties of modified concrete include: compressive strength, tensile strength, Bending strength, electrical resistivity and water absorption. The results indicate that the use of zeolite and micro-nano bubble in concrete increases the mechanical properties and the durability of concrete. The greatest improvement is related to the two-phase samples from the combination of 10% zeolite and 100% micro-nano bubble, which compressive strength, tensile strength, bending strength and electrical resistivity increase by 15, 14.88, 5.65 and 194.12% respectively, and water absorption decrease by 25.22%. In general, according to the results, it can be concluded that zeolite and micro-nano bubble, improve the mechanical properties and durability of concrete and their combination has the most positive effect on modified concrete.
