<p>The present invention relates to a self-complementary composite including: 15wt% to 65wt% of a cement coupling agent; 25wt% to 75wt% of fine aggregates; 0.01wt% to 15wt% of a polymer admixture; and 0.0wt% to 15wt% of water, wherein the polymer admixture includes 50wt% to 99wt% of polymethyl methacrylate-butyl acrylate for improving strength and attaching force, 0.1wt% to 30wt% of an epoxy resin for providing bonding force, durability, and a self-complementary function, 0.1wt% to 20wt% of polystyrene-butyl acrylate for improving an anti-acid property and an anti-alkali property, and 0.1wt% to 20wt% of sodium polyacrylate for improving strength and durability. According to the present invention, a cement coupling agent having strength, durability, and a self-complementary function, and a polymer admixture having docility, bonding force, an anti-acid property, a heat resisting property, and durability, and having a self-complementary function are used, thereby strength, docility, fluidity, and durability being remarkably improved. In addition, because a self-complementary cement coupling agent and a polymer admixture that can restore and cure performance lowering elements such as cracks when a damaged part of a concrete structure is processed are used, maintenance demands can be restrained and related maintenance cost can be reduced by improving maintenance and restoration effects without requiring additional constructions due to an additional crack.</p> |
