A multi-component mortar system contains a curable aqueous-phase aluminous cement component A and an initiator component B in aqueous-phase for initiating the curing process. Component A further contains at least one plasticizer, water, and at least one blocking agent selected from phosphoric acid, metaphosphoric acid, phosphorous acid, and phosphonic acids. Component B contains an initiator, at least one retarder, at least one mineral filler, and water. A multi-component system is useful, which is ready-for-use, for chemical fastening of anchoring means, preferably of metal elements, in mineral surfaces, such as structures made of brickwork, concrete, pervious concrete or natural stone as well as its use for chemical fastening of anchoring means.

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.
