Popis: In this study, the physical properties of the material were tested to ensure the applicability of the filling-type fireproof construction method when using spraying materials, and the changes in the material in different filling locations were evaluated. The filler, ET-1013 mixture without admixture, showed proper fluidity. When using the lower filling method, cracking and sagging occurred over time because of the increase in internal pressure. At the same time, cracking and deflection did not occur in the case of the upper filling method. The filling tests were performed using manufactured 1,000 and 3,000 mm columns. In the case of the lower filling method, cladding steel plates of the column underwent out-of-plane buckling, and the material separation occurred.
