Numerical analysis of metal oxide nanoparticles effects on permeability of hydraulic structures

Ali sheykhi Garousi, Farinaz zamani

The concrete permeability coefficient of the heavy water tank of nuclear reactors is very important in concrete structures of hazardous liquids tanks. Therefore, metal oxide nanoparticles effects on the permeability of hydraulic structures were numerically analyzed in this research. The experiments of this project and the obtained results were examined. In this project, 36 samples (18 cube samples and 18 cylindrical samples) for the control mixture design and more than 75 samples with different percentages of nanoparticles (0.5, 0.1, and 0.15% nano metal oxide) were prepared. The obtained results from the experiments showed that the permeability coefficient of concrete samples containing titanium nanoparticles reduced by increasing nanomaterial replacement percentage and reached to minimum in replacement of 0.1%. This is because using nanoparticles could fill the tiny and even nano-sized pores of concrete according to the tiny structure of concrete and presence of pores in nano size and reduce concrete permeability by providing the condensed structure.
