NOVELTY - Manufacture of water-purifying concrete comprises spraying graphene-silicon based nanohybrid material on surface of the concrete, where nanohybrid material comprises 2.64-3.33 wt.% ethyl orthosilicate, 0.29-0.37 wt.% graphene oxide, acid to adjust pH to 3-4, and balance solvent of water and/or absolute ethanol. USE - The method is used for manufacturing water-purifying concrete. ADVANTAGE - The concrete has reduced amount of nano-hybrid materials, improves contact area between nano-hybrid material and polluted water body, has improved efficiency of sewage purification, overcomes problem of poor combination of graphene and concrete, and has improved durability of water purification function.
