Concrete structural elements are known to have good inherent fire performance. Concrete is non-flammable, non-combustible, and more robust in fire than other structural systems as it can absorb a greater amount of heat before reaching critical overload.
Concrete simply cannot be set on fire. As it does not burn, concrete does not emit any environmentally hazardous smoke, gases or toxic fumes. In addition, unlike some plastics and metals, concrete will not drip dangerous molten particles. Concrete also acts as an effective fire shield as its mass confers a high heat storage capacity while its porous structure provides a low rate of temperature rise.
The majority of concrete structures are not destroyed in a fire, and can therefore be repaired easily, minimising inconvenience and cost. Everyone from private owners and insurance companies, to local and national authorities, share the economic benefits of fire safety, and its contribution to the sustainable upkeep of critical infrastructure.
Concrete’s superior fire performance also ensures that buildings remain stable during fire. This enables occupants to survive and escape, while also allowing emergency services to work safely.
