CONCRETE STRUCTURE FOR ARREST ALKALI IONS LEACHING FROM CONCRETE SURFACE TREATMENT APPARATUS AND METHOD FOR CONCRETE

摘要

The present invention relates to a concrete structure for inhibiting the leaching of alkali ions and an apparatus and a method for treating a concrete surface thereof. More particularly, the present invention relates to a method and apparatus for preventing alkaline leaching, And to provide a concrete structure for suppressing the leaching of alkali ions and an apparatus and a method for concrete surface treatment for the same, which can improve the stability of the ecological environment and improve the inner closure of the concrete. According to an aspect of the present invention, there is provided a method for surface treatment of concrete for inhibiting alkali ion leaching, the method comprising the steps of: vacuuming a space in which concrete produced through a predetermined process is placed into a vacuum state; A carbon dioxide injection step of injecting carbon dioxide into the vacuumized space; And controlling an influence factor for promoting carbonation on the surface of the concrete to control the influence factor for forming a calcium carbonate layer on the surface of the concrete. The present invention also provides a concrete surface treatment method for suppressing alkali ion leaching.
