Differential Thermal Analysis (DTA) – Lab Test – Assessment of qualitative and quantitative composition of sample of concrete X-ray Diffraction (XRD) – Lab Test – To determine the extern of deterioration in concrete subjected to fire Differential Thermal Analysis (DTA) DTA is used to study the physical and chemical changes that occur in a material(…)
Fire Proof
FIRE PROOF CONCRETE
At the high temperatures experienced in fires, hydrated cement in concrete gradually dehydrates, reverting back to water (actually steam) and cement. This results in a reduction of strength and modulus of elasticity (stiffness) of concrete. In some fires, spalling of concrete occurs – fragments of concrete break loose from the rest of the concrete, sometimes(…)
