▎ 摘　　要

NOVELTY - Nano-modified inorganic mineral water-proofing agent comprises 80-95 pts. wt. inorganic mineral powder, 2-10 pts. wt. nano- material, and 0-0.5 pts. wt. coupling agent, where the nano material is nano graphene, nano stearate, nano calcium carbonate and/or nano titanium oxide. USE - The water-proofing agent is useful for concrete structure protection and waterproof mortar used in concrete structure (claimed). ADVANTAGE - The nano-modified inorganic mineral water-proofing agent has low doping amount when preparing waterproof concrete or waterproof mortar, and realizes the integrated waterproof protection function at the same time, which satisfies the low cost of engineering and high performance requirement; has better application effect and can reduce the production cost of waterproof mortar or waterproof concrete protective structure; and can realize the whole hydrophobic of mortar or concrete structure under the premise of not reducing the mechanical and durability, and has good comprehensive performance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing nano-modified inorganic mineral water-proofing agent.
