LIQUID AMINE COMPOSITION, TWO-COMPONENT MATERIAL FOR MAINTENANCE AND REINFORCEMENT, AND MAINTENANCE AND REINFORCEMENT METHOD OF CONCRETE STRUCTURE USING THE SAME

摘要

PPROBLEM TO BE SOLVED: To provide a two-component material for maintenance and reinforcement comprising a composition consisting of a main resin including an epoxy resin as a main component and an amine composition in which workability of the composition before mixing is excellent and thixotropy after the mixing is large enough to prevent sagging. PSOLUTION: The amine composition that is liquid in room temperature at least comprises [A] an amine compound and [B] hydrophobic silica particles. The two-component material for maintenance and reinforcement uses the amine composition as a curing agent. A maintenance and reinforcement method uses a curable epoxy resin composition obtained by mixing the two-component material for maintenance and reinforcement. PCOPYRIGHT: (C)2003,JPO
