NOVELTY - Method for improving dispersion uniformity of copper slag powder in cement sand/paste involves mixing copper slag powder and graphene oxide in mass ratio of 1:(0.2-0.4), obtaining graphene oxide/copper slag mixed powder, uniformly dispersing the graphene oxide/copper mixed powder in ionic dispersant solution, obtaining graphene oxide/copper slag slurry, adding cement mortar raw material or cement, mixing uniformly and obtaining forming copper slag-cement slurry. USE - Method for improving dispersion uniformity of copper slag powder in cement sand/paste (claimed). ADVANTAGE - The graphene oxide has excellent dispersing effect with respect to copper slag powder, and the copper slag powder is easy to adsorb and forms intercalation structure, thereby improving the dispersion uniformity of copper slag powder in cement sand/paste.
