Title:
CONCRETE MANUFACTURING METHOD USING NITROGEN DISSOLVED WATER AND METHOD FOR MANUFACTURING REINFORCED CONCRETE STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2018/189915
Kind Code:
A1
Abstract:
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.
