At extreme high temperatures which are generally experienced in fires, hydrated cement in concrete slowly gets dried out, returning to water (in reality, steam) and cement. This leads in a lessening of strength and modulus of flexibility (stiffness) of concrete. In a few fires, spalling of concrete happens – parts of concrete loosen up from […]
