OverviewWith high frequency of industrial fires in the recent past, fire protection of concrete has become an important design criterion for protection and preservation of the structural concrete.
Exposure of concrete surface to fire may result in explosive spalling due to trapped vapor pressure.
Concrete reinforced with Duracrete Fibre provide channels for the vapor pressure to dissipate as the fibre melts on exposure to fire.
The reduction in spall damages provides protection to steel reinforcement against direct exposure of to fire, which may otherwise conduct heat and accelerate the action of high temperature.
Incorporation of Duracrete fibres helps delay structural failure allowing more time for safe evacuation from the building.
