Properties of Fiber Reinforced Concrete (FRC) – Types, Recently plastic fibers like polypropylene fibers are incorporated in the high-performance concrete mix to take care of the brittle behavior and to improve the fire resistance property of high strength concrete. Concrete made with a very low w/c ratio (w/c ratio of . or less) is inferior with respect to fire resistance to normal concrete
Strategies for enhancing fire resistance of high-strength The presence of steel or polypropylene fibers in a concrete mixture minimizes the extent of fire-induced spalling and thus enhances fire resistance of any concrete member. Results from experimental studies show that the addition of polypropylene fibers to concrete (about . to .% by volume) minimizes spalling in HSC structural members
An Explorative Study into the Influence of Different Fibers -- &#; This study aims to explore the impact of different fibers on the explosive spalling resistance, residual compressive strength, residual flexural tensile strength, and mass loss of self-compacting concrete (SCC) after heating to elevated temperatures. The fiber types, fiber contents, and target temperatures are selected as the tested variables.
