High temperature has a profound impact on the physical and chemical properties of cement and concrete, crucial in various engineering applications such as in construction in hot climates, refractory concrete for furnaces, and post-fire analysis of concrete structures. Understanding the behavior of concrete under high temperatures is essential for designing structures that are durable and safe under such conditions. This analysis involves exploring the thermal stability, dehydration of chemical components, and the resultant changes in microstructure and mechanical properties.
