Abstract: The composites of polycarboxylate superplasticizer (PCs) and raphene oxide (GO) (PCs/GO) was prepared by intercalation of GO and methacrylic acid (MAA), sodium allyl sulfonate (SAS) and methacrylate polyoxyethylene ether (MPE). The application results indicated that PCs/GO could regulate to form ordered micromorphology consisted by polyhedron products, which exhibited obvious reinforcing and toughening effect. Meanwhile, it was found that GO could generate flower-like and polyhedron products in the holes and cracks to repair the holes and cracks. The research result has positive significance to preparation of the cement composites with defect-free structure, high strength, high toughness as well as long service life.
