Provided are a concrete manufacturing method capable of preventing neutralization of concrete and oxidation of a reinforcing rod in reinforced concrete, and a method for manufacturing a reinforced concrete structure using the same. The concrete manufacturing method uses nitrogen dissolved water and is characterized by including: a step of generating nitrogen dissolved water by injecting nitrogen gas into water to replace oxygen and carbon dioxide dissolved in the water with nitrogen; and a step of generating a ready-mixed concrete by kneading the nitrogen dissolved water, cement, an aggregate, and an admixture. The method for manufacturing a reinforced concrete structure is characterized by forming a reinforced concrete structure using a ready-mixed concrete manufactured by a concrete manufacturing method using nitrogen dissolved water.

Dispersion-based ready-to-use grout formulations, methods of making such dispersion-based ready-to-use grout formulations, and the resultant grout products that perform as reactive resin grout products. The grout formulations of the invention at least include a water-based acrylic polymer dispersion binder and a water-based acrylate copolymer dispersion binder, in combination with one or more of an alkaline cross-linker, one or more silane adhesion promoters and/or a micro-fiber filler, along with various other constituents, to provide one-part ready-to-use grout formulations that require no mixing prior to use thereof. The resultant grout products of the invention meet performance standards of epoxy grout products, without requiring mixing of composition parts and without any adverse side effects.
