Abstract
One of the major concerns of High-strength concrete is its fire resistance. In some of our earlier high-rise RC projects, the most straight-forward measurewas taken to avoid the fire concerns : to provide additional finishing with normal-strength mortar layers all over the column surface. On the other hand, it has been known that the inclusion of polypropylene fibers improves the fire resistance of high-strength concrete by creating a pore structure that enables steam to dissipate. In this report, workability, compressive strength, durability, and fire resistance of the fiber concrete are summarized, and the application of such a concrete to an actual building construction is introduced.
