▎ 摘  要

NOVELTY - Nano recycled concrete comprises fly ash, polyvinyl alcohol and graphene oxide which form graphene oxide (GO)-polyvinyl alcohol hydrogel doped fly ash (PVAH-FA). USE - The concrete is useful in preparing coastal assembling structure comprising but is not limited to well cover, rainwater grate, underground pipe gallery, egg-shaped water tank, underground duct piece, honeycomb beam, and overlapped beams/plate (claimed). ADVANTAGE - The concrete: has excellent adhesion water-retaining property and adjacent thin-layer interface bonding property; is combined with graphene oxide and PVA electrolyte to form a micro-capacitor to avoid formation of corrosion battery in the concrete thin layer; and has excellent marine durability and excellent application prospects when used in coastal assembling structure engineering. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a processing technology of the nano recycled concrete.
