In the present study, the sedimentation mechanism of SiO2 nanoparticles (NS) on Graphene Oxide (GO) nanosheets by hydrolysis of Tetra Ortho Silicate (TEOS) in water/ethanol solution was investigated. In the first part, the possible interactions among nanoparticles by UV-Vis and Transmission Electron Microscopy (TEM), and in the second part, the mechanical properties of nanocomposite materials contain NS and GO (NS&GO) by molecular dynamic simulation (MDS) were discussed. Finally, the application of single and hybrid nano materials on 12 kinds of the mixture of mortars containing natural pozzolan was compared with mechanical properties. the improvement of dispersion of NS on GO nanosheets was visible in TEM. Also, the results of MDS demonstrate 75% increase in tolerable stress and 250% increase in Young’s modulus in nanocomposite compared with single nano-SiO2. 28-day compressive and tensile strength mortars containing NS&GO increased by 31% and 100%, respectively and compared with the control. As a result, appropriate dispersion and distribution of nanoparticles, NS&GO through nucleation properties, and zeolite through pozzolanic properties improved the mechanical function of mortars.
