NOVELTY - Cement mortar composited by graphene oxide comprises cement, water, sand, water reducer and graphene oxide. The preparation of cement mortar composited by graphene oxide comprises mixing and stirring all raw materials to obtain cement mortar. The cement and sand mass ratio is 1:3. The water cement ratio is 0.35. The graphene oxide is 0.01-0.07% of cement solid mass. The water reducer is 0.198-0.306% of cement solid mass. USE - Cement mortar composited by graphene oxide. ADVANTAGE - The material has low cost, big diameter and thick layer.
