HIGH-STRENGTH SPUN CONCRETE COLUMN USING HEAT-PROOF FIBER FOR THE PREVENTION OF SPALLING AND MANUFACTURING METHOD THEREOF

摘要

The present invention relates to a high intensity centrifugal molding concrete pillar structure, and a manufacturing method using a heat resistant fiber pokyeol , and more particularly to high-strength concrete for preventing blended pokyeol insoluble fiber while applying a heat island within an autoclave (autoclave) cure that is used to shorten the manufacturing time of the high intensity centrifugal molding concrete columns and suppress the temperature rise of the internal reinforced concrete relates to a high strength to centrifugal molding concrete pillar structure, and a manufacturing method using a heat resistant fiber pokyeol. High intensity centrifugal molding concrete columns according to the invention is heat resistant fiber (2) are mixed, the heat-resistant fiber at a high temperature steam curing is performed in the centrifugal molding (2) is not melted, as in case of fire heat resistant fiber (2) is melted moisture to form a passage through which exhaust pillar (1) there is an advantage in that moisture inside the moisture can effectively be discharged to the outside to effectively prevent the evaporation occurs that pokyeol phenomenon occurs. ;
