ECO-FRIENDLY ORGANIC-INORGANIC HYBRID COMPOSITION FOR ENHANCING DURABILITY OF CONCRETE STRUCTURE AND METHOD FOR PROTECTING SURFACE OF CONCRETE STRUCTURE THEREWITH
The present invention relates to an environmentally-friendly organic/inorganic complex composition and a concrete structure surface protection method using the same. According to the present invention, the environmentally-friendly organic/inorganic complex composition comprises 5 to 85 wt% of a performance modification binder, 10 to 85 wt% of fine aggregates, and 5 to 40 wt% of water. The performance modification binder comprises: 10 to 85 wt% of high early strength Portland cement; 5 to 50 wt% of amorphous calcium sulfoaluminate; 1 to 30 wt% of tricalcium aluminate; 1 to 30 wt% of gibbsite; 1 to 20 wt% of germanium; 1 to 20 wt% of gypsum; 1 to 15 wt% of dolostone; 0.1 to 10 wt% of titanium oxide; 0.1 to 10 wt% of magnesium oxychloride; 0.1 to 10 wt% of ethylene vinyl acetate-polyvinyl chloride copolymer; 0.1 to 10 wt% of ethylene propylene rubber copolymer; 0.1 to 10 wt% of ethylene fluoroethylene copolymer; and 0.1 to 10 wt% of methyl(meta)acrylate-butylacrylate copolymer. Accordingly, provided are excellent strength, wear-resistance, UV-resistance, salt resistance, neutralization resistance, bonding property, freezing/thawing resistance, and durability, thereby lengthening a performance period of a concrete structure, reducing maintenance/repair expenses, and increasing constructability.
