Saline-alkali area concrete salt erosion transmission inhibition material

The invention discloses a saline-alkali area concrete salt erosion transmission inhibition material. The saline-alkali area concrete salt erosion transmission inhibition material comprises the following components by weight: 10-15 parts of epoxy modified polysiloxane, 15-20 parts of polypropylmethylsilsesquioxane, 15-20 parts of mercaptopropyl silane, 5-10 parts of short-fluoro chain fluorine-containing polyacrylate, 10-15 parts of nano alumina, and 20-30 parts of water. The concrete erosion resistant material provided by the invention has excellent protective performance to saline-alkali area concrete, and can effectively inhibit salt erosion and guarantee the concrete service life. The material provided by the invention utilizes the nano-filling hole blockage effect of nano alumina to reduce concrete porosity so as to improve compactness.
