However, this would buck considerable time. Bricks are toughened by conflagration, and therefore, are able to withstand fire longer. Concrete is very much toughened with steel. If the reinforcement is superficial, the extension of the steel causes the concrete to expand. The expansion causes fissures.Timber is the adversely affected by conflagration. The ignition point of timber is lower than other elements. Exposure to heat and oxygen results in incineration. conflagration starts with the charring of the surface, and thereafter, the structural integrity is compromised. Prolonged fire burns the timber to ashes. Metal is extensively affected by fire. Heat elevates the kinetic energy of the atomic configuration of the metal. The structure weakens and wantons strength. At 500 degrees, it may loose 5 0% of its strength. Further, steel may melt slightly and warp slightly in adverse heat (Dodson,
