Main causes of fire in buildings. Fire triangle. ISO 834 fire normalized curve. Fire behaviour of the materials: wood, natural stones, concrete, ceramics, glass, polymers, paints and varnishes. Fire behaviour of the concrete, steel and timber structures. Evolution of the strength and stiffness of the concrete, steel and timber with the temperature increase. Materials classes of reaction to fire performance classes – EN 13 501. Building element fire behaviour – R E I. Protection of the structural elements to the fire action: concrete, steel and timber. Coatings with concrete, lightweight concrete, expanded clay, plasters, glass wool and rock wool, vermiculite boards, calcium silicate boards, shot mortars and intumescent paintings.
