Abstract:Graphene oxides nanosheets (GON) dispersion solution was prepared by controllable oxidizing and ultrasonic dispersion for graphite.The effect of GON on microstructure and properties of cement based composites were investigated.The results indicated that GON can regulate formation of regular polyhedron-like hydration crystals and assemble the polyhedron-like crystals into regular microstructure with flower-like morphology,which resulting in obviously improving in compressive and flexural strength for the cement composites.The formation mechanisms were also presented and think that GON has template role in forming cement hydration crystals and can make the cement hydration products to form polyhedron-like crystals.The polyhedronlike crystal can form regular micromorphology by interweaving way.The research result has a positive meaning to achieve regular microstructure and high performances and longer service life.
