The present invention relates to a waterproof material composition for concrete, which is added during the production of concrete, as well as waterproofing performance can be ensured excellent anti-rust properties to prevent the reinforcement of the steel oxidized by salts in salt areas and corrosion environments, such as salt easy to penetrate In addition, the purpose of the present invention is to suppress corrosion of reinforced concrete and greatly increase the durability. In order to achieve the above object, the present invention provides a plies which are artificial pozzolanic activators with respect to 100% by weight of the total composition. Ash 40-60 wt%, silica fume 6-12 wt%, redispersible powder resin 0.5-5 wt%, higher fatty acid metal salt 5-11 wt%, high performance water reducing agent 1-6 wt%, bipolar inorganic salt 18-34 wt% Waterproofing for concrete having a rust prevention function, characterized in that it comprises 1% to 5% by weight of tannin as an antioxidant To provide the ash composition. |
