Strength-strengthening method of concrete-structures with overweight blast furnace flag powder

摘要

The present invention discloses a method for strengthening the strength of a concrete structure including blast furnace slag fine powder. The method for strengthening the strength of a concrete structure including blast furnace slag fine powder according to the present invention is characterized in that an alkali solution is applied to the concrete structure, whereby a large amount of blast furnace slag is replaced, thereby simplifying the concrete structure of less than a predetermined strength. There is an effect of recovering the compressive strength through the construction method.
