Preparation and properties of graphene oxide modified concrete
Huangshan University, School of Civil Engineering and Architecture, HuangShan 245041, China
Graphene oxide is often used in cement-based materials due to its high strength, toughness and strong surface activity, which can not only improve mechanical properties but also enhance durability. Modified concrete with different graphene oxide dosings (0,0.04%, 0.08% and 0.12% (mass fraction)) was prepared by doping graphene oxide into concrete. The effects of graphene oxide dosage on the microstructure, crystal structure, mechanical properties, slump and porosity of the modified concrete were studied. The results show that an appropriate amount of graphene oxide doping accelerates the hydration reaction of the modified concrete, refines the pore structure and improves the density. With the increase of the doping amount of graphene oxide, the compressive strength and flexural strength of the modified concrete first increase and then decrease, while the slump and porosity first decrease and then increase. When the doping amount of graphene oxide is 0.08% (mass fraction), the compressive strength and flexural strength both reach the maximum values of 46.3MPa and 7.5 MPa respectively at 28 days. The slump and porosity reached the minimum values of 27.6 mm and 25.1% respectively. It should be noted that with a graphene oxide content of 0.08% (by mass fraction), the comprehensive performance of the modified concrete is the best.
