NOVELTY - Preparing high-strength building concrete involves using acid-modified graphene oxide which is supported in pores of mesoporous glass microbeads with thickening stabilizer, water reducing agent, defoamer, cement matrix, followed by mixing water, pouring molding and curing to produce high-strength concrete, mixing graphene oxide with acrylic monomer, and then adding cross-linking agent and initiator, and freeze-drying to obtain modified graphene oxide, adding modified graphene oxide to dimethylformamide to prepare an organic dispersion, and then adding mesoporous glass beads, dispersing uniformly and pressurizing graphene oxide into micropores of glass microbeads, and drying to prepare glass beads loaded with modified graphene oxide. USE - Method for preparing high-strength building concrete. ADVANTAGE - The method enables to preparing high-strength building concrete which has wide application prospects. DETAILED DESCRIPTION - The glass microbeads of graphene are thoroughly mixed with thickening stabilizer, water reducing agent, defoaming agent, and calcium oxide-containing cement matrix, and stirred with water, poured into mold for forming, and then released and cured for 24 hours to obtain desired product.
