Cement, Refractory

Refractory cement is a specialized type of cement designed for high-temperature applications, for example Calcium-Aluminate Cement, as opposed to Portland Cement. It is used in industries where extreme heat, such as in furnaces, kilns, and incinerators, is encountered. Refractory cement is made from materials that can withstand and retain their strength even at very high temperatures, typically above 1,000°C (1,832°F). It is formulated with high-alumina or silica content to provide excellent heat resistance and insulation properties. The cement is mixed with aggregates and water to create a refractory concrete, which is used to line the interior of high-temperature equipment to protect it from heat damage and ensure efficient operation. Refractory cement is crucial for industries that require durable and thermally stable materials to withstand extreme heat conditions.
