The present invention relates to a waterproofing agent composition for mixing concrete which has abrasion resistance by using metakaolin with high reactivity, wherein the waterproofing agent composition comprises, based on 100 parts by weight of the composition, 55 to 75 parts by weight of fly-ash or slag having pozzolanic activity; 6 to 12 parts by weight of silica-fume; 0.5 to 5 parts by weight of a redispersible powder resin; 6 to 12 parts by weight of higher fatty acid-based metallic salts; 4 to 9 parts by weight of a water-reducing agent with high efficiency; and 6 to 12 parts by weight of metakaolin. The waterproofing agent composition has not only improved waterproof properties but also improved abrasion resistance. |
