Fire resistance is one of the key factor which aids toward durability a structure. Concrete most widely used construction material and also an effective for structural fire protection. Physical thermal properties are to measure concrete. Three main reasons concrete are: non-combustible, non-toxic, low conductivity (concrete retain slow rate heat transfer). The lower value behaves like perfect s...

Prediction of concrete performance at high temperatures is of great importance, in particular for safety evaluation of concrete structures in fires in tunnels and high buildings or in thermal hazard situations like hypothetical core disruptive nuclear accidents. High temperatures induce strong physical and chemical changes in the micro-structure of concrete that affect its mechanical behaviour....
