1. An anti-corrosive concrete grouting material for coastal structure connection, wherein the anti-corrosive concrete grouting material for coastal structure connection consists of the following raw materials in parts by weight: 1 part of expansible compound cement, 1-2 parts of slag sand, 0.05-0.2 part of fly ash, 0.005-0.05 part of polyvinyl alcohol, 0.0002-0.002 part of graphene oxide, 0.005-0.01 part of a water reducer, 0.005-0.01 part of an adjusting admixture, 0.0001-0.001 part of a defoaming agent, 0-0.05 part of a mineral admixture and 0.25-0.55 part of water, wherein:
the polyvinyl alcohol and graphene oxide are prepared into a GO-PVA prepolymer solution by adopting an in-situ polymerization and intercalation method, and
the fly ash is coated with the GO-PVA prepolymer solution to obtain GO-PVAH@FA.
