A comparative study: Effects of different nanoparticles on the properties of gold mine tailings containing cement mortars

•Effects of different nanoparticles on cement mortar were investigated.•The nano-SiO2 improved the compressive strength by 11.46% of reference.•The gold mine tailings containing mortars with 1.5 wt% nano-CuO had a more compact structure.•The water absorption decreased as 45.22% of reference by 2.5 w...
