▎ 摘　　要

NOVELTY - High-waterproof corrosion-resistant concrete comprises 10-20 pts. wt. graphene oxide, 10-20 pts. wt. sepiolite, 8-10 pts. wt. shell powder, 3-5 pts. wt. water-soluble silicate and 20-60 pts. wt. cement. USE - The concrete is useful for marine biological engineering (claimed). ADVANTAGE - The concrete maintains long-term stability in seawater environment. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the concrete, comprising mixing graphene oxide, sepiolite, shell powder, water-soluble silicate and cement, ball milling for 4-6 hours, then adding nano silicon dioxide fibers, mixing under stirring condition for 1-3 hours and discharging to obtain final product.
