Concrete, Refractory

Refractory concrete is a specialized type of concrete designed for high-temperature applications. It is composed of heat-resistant aggregates, such as high-alumina or silica, and a binder, typically a refractory cement. The concrete mixture is formulated to withstand extreme temperatures, often exceeding 1,000°C (1,832°F), without losing its strength or structural integrity. Refractory concrete is commonly used to line the interior of furnaces, kilns, and other industrial equipment where thermal insulation and resistance to heat and chemical corrosion are required. It provides a protective barrier that prevents heat transfer, maintains structural stability, and prolongs the lifespan of the underlying structure in high-temperature environments.
