Anti-Spalling Concrete
Abstract Anti-spalling concrete is usually composed of concrete matrix and fibers and/or air entraining agent. The polypropylene fiber is the most effective filler to fabricate anti-spalling concrete. The microchannels formed by melted polypropylene fibers supply evacuation exits for gases and water vapor, decreasing the pore pressure and temperature stress in concrete. If the air entraining agent is used, a more permeable network can be formed in concrete at high temperature because of the entrained air voids. The anti-spalling concrete endows high fire resistance with infrastructures under complex environment, thus decreasing the building crumble accident rate and the corresponding economic loss and casualties.
