Quantifying Fire Insulation Effects on the Fire Response of Hybrid-Fiber Reinforced Reactive Powder Concrete Beams

The fire performance of reinforced reactive powder concrete (RPC) beams has raised much concern due to the sensitivity of these beams to high temperature and relatively lower fire resistance. To achieve the fire-resistance ratings as specified in building design codes, a fire insulation layer is often required. However, very limited research has been conducted on the effect of fire insulation on the fire resistance of reinforced RPC beams....
