Brief Introduction to the Application of Graphene Oxide in Concrete
Keywords
Graphene oxide, concrete, cement, nuclei
Graphene oxide (GO) is an intermediate product in the preparation of graphene. Due to its unique lamellar structure and the structure contains special carboxyl, hydroxyl and other characteristics.
Graphene oxide can be regarded as an unconventional type of soft material with properties of polymers, colloids, films, and amphiphiles. Graphene oxide has long been regarded as a hydrophilic substance because of its excellent dispersibility in water.
When used in combination with cement materials, it can promote the cement to produce special-shaped hydration crystals, which can significantly increase the toughness of the cement.
Graphene oxide has a nano-size effect, which can promote and accelerate the hydration reaction of cement and improve the overall strength of cement.
Graphene oxide has the property of preventing cement cracks, so it can improve the crack resistance of cement.
Due to the unique carboxyl and hydroxyl properties of graphene oxide, it can form a closer cross-linking reaction with cement molecules, thereby enhancing the compactness of cement concrete materials and optimizing the internal void structure of concrete.
