Effect of Polypropylene and Steel fibers on Fire Resistance of UHPC

Ultra high performance concrete is a relatively new class of concrete, additional research is needed to understand more fully the factors affecting the development of its physical and mechanical characteristics. Thus, one of the critical aspects for the successful production of high-performance concrete is to know the main components affecting the production of UHPC and their proportions. Eventually, design codes will need to be revised to incorporate the necessary requirements for the safe and efficient use of high-performance concrete. Since the strength development and durability characteristics of high-performance concrete may be different from ordinary concrete, it follows that actual performance of UHPC using steel fibers and polypropylene under elevated temperature should be studied.
