This study presents the results of fire resistance tests of a loaded cast iron column with circular hollow sections (CHS), protected against fire with fire protection mortar. In addition, unloaded columns, protected with the same mortar, were tested in order to determine the relationship between the load and fire protection efficiency.Also, twomore unloaded columnswere added, whichwere protectedwith a different type of fire protectionmortar. The results obtained indicate that cast iron columnsmay be protected not onlywith reactive, but alsowith passive fire protectionmaterials. The required fire protection thickness may be determined based on tables from tests of steel elements pursuant to the EN 13381 European Standard System. The existing methods for the determination of the critical temperature of steel, provided i.a. in EN 1993-1-2, may also be successfully used for cast iron structures.
