Abstract: The present invention relates to an apparatus for manufacturing fiber-reinforced concrete through shooting after inserting bubbles into normal concrete and a method for manufacturing the same, which: form fiber-mixed concrete in which the bubbles, fiber-mixed materials, and silica fume are mixed in the normal concrete or form the fiber-mixed concrete in which aggregates, water, and the bubbles are put into and mixed with a mixture, in which cement, the fiber-mixed materials, and silica fume are mixed; and then shoots the fiber-reinforced concrete in which excessive air included in the fiber-mixed concrete is reduced by spraying the fiber-mixed concrete with the high-pressure air when the fiber-mixed concrete is discharged, and of which a slump, drastically increased due to the large amount of bubbles, is reduced to a range of the slump of the normal concrete, thereby improving the production capacity of the fiber-reinforced concrete and shortening operating time.

Abstract: The present disclosure relates to a method for cultivating coffee bean with improved growth and contents of nutritional ingredients, including: (a) a step of preparing diluted deep sea water by mixing undiluted deep sea water with water; and (b) a step of irrigating coffee tree with the diluted deep sea water prepared in the step (a), coffee bean with improved growth and contents of nutritional ingredients, cultivated by the method, and a processed food using the coffee bean.
