NOVELTY - Road curb comprises cement, construction solid waste recycled aggregates, mineral admixtures, graphene oxide, water and additives in a mass ratio of (30-50): (80-200): (10-30): (0.015-1.000): (12-40): (0.020 to 1.000). USE - Road curb. ADVANTAGE - The road curb tightly adheres to the surface of the hole, effectively prevents the regenerated aggregate from absorbing water to a certain extent, and overcomes the problems of large water absorption and unstable performance of the solid waste aggregate of construction, enables graphene oxide to promote cement hydration and compact the concrete structure, for effectively blocking the intrusion of harmful ions and improves the performance of the matrix. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing the road curb, which comprises (A) crushing and sorting the construction solid waste sequentially to obtain the construction solid waste regenerated aggregate; (B) dispersing graphene oxide in water to obtain a graphene oxide suspension; (C) immersing the regenerated building solid waste aggregate in the obtained graphene oxide suspension and stirring fully to make the graphene oxide coat the surface of the aggregate; (D) mixing the obtained graphene oxide-construction solid waste recycled aggregate mixture, cement, mineral admixtures, water and admixtures fully with a stirring device to obtain a mixed slurry; (E) putting the mixed slurry into a forming mold, tapping it, and demolding after 24 hours to obtain a test block; and (F) putting the test block in a curing room with a temperature of (20 plus minus 2) degrees C and a humidity of 95% or more for 28 days.
