WATERPROOF COMPOSITION FOR CONCRETE STRUCTURE

摘要

PURPOSE: A concrete structure for the repair of a waterproof composition is provided to increase resistance to weather and to provide a waterproof function. CONSTITUTION: A concrete structure for the repair of a waterproof composition is made of water-based epoxy resin, polyamine-based hardener, anion surfactant, non-ion surfactant, and water. The water-based epoxy resin is 10~45 weight%. The polyamine-based hardener is 10~35 weight%. The anion surfactant or non-ion surfactant is 0.1~5.5 weight%. Holes and gaps in a concrete structure are filled in order to maintain the rigidity of the concrete structure.
