NOVELTY - Preparing high elastic modulus graphene reinforced recycled concrete comprises (i) taking cement, sand, coarse aggregate , water, nano materials and water reducing agent in the mass ratio of 1:1.4-1.6:2.6-3:0.28-0.32:0.0001-0.0005:0.01-0.05; (ii) uniformly mixing nano material, water reducing agent and water, dispersing ultrasonically for 30-60 minutes, to obtain a suspension; (iii) uniformly mixing cement, sand and coarse aggregate in a blender for 3-4 minutes; and (iv) uniformly mixing step (ii) and (iii) products for 3-5 minutes and molding, to obtain the final product. USE - The method is useful for preparing high elastic modulus graphene reinforced recycled concrete (claimed). ADVANTAGE - The concrete is compact and has high compressive strength.
