Introduction of High Temperature Refractory Cement
High temperature refractory cement, also known as high alumina cement or aluminous cement, is a specialized type of hydraulic cement. It is made of natural bauxite or industrial alumina and calcium carbonate (limestone) in a certain proportion. Besides, high temperature refractory cement is obtained by heating a mixture of limestone (calcium carbonate) and bauxite (aluminum ore) in a kiln to high temperatures about 1500℃(2732℉). The resulting clinker is finely ground to produce high temperature refractory cement. In addition, it is also made by melting bauxite and limestone.

Store high temperature refractory cement in a dry area away from moisture and humidity. Besides, keep the bags tightly sealed to prevent moisture absorption. Additionally, follow proper lifting and handling techniques to avoid strain or injury.
High Performance Refractory Cement Maintenance Method
Maintaining high temperature refractory cement structures involves regular inspections, cleaning, and addressing any signs of damage or deterioration. So here are some maintenance methods for high temp refractory cement.
Conduct routine inspections of the high temperature refractory cement structures to identify any cracks, spalling, or other signs of damage. Inspect both the surface and underlying structures to catch any issues early on.
Like protecting refractory bricks, keep the high temperature refractory cement surfaces clean by removing dirt, debris, and stains. Use mild detergent and water for regular cleaning. What’s more, avoid using harsh chemicals or abrasive cleaners that can damage the cement.
Promptly repair any cracks or spalling in the High temperature refractory cement. Clean the damaged area thoroughly, removing loose material and debris. Besides, use appropriate repair materials, such as calcium aluminate-based repair mortars. Ensure proper curing of the repair materials for optimal bonding and strength.
If the high temperature refractory cement is exposed to chemicals or corrosive substances, take appropriate measures to protect the surface. Apply suitable chemical-resistant coatings or sealants to prevent damage and ensure long-term durability.
High temperature refractory cement can be susceptible to water infiltration. In addition, ensure proper drainage and waterproofing measures to prevent water from penetrating the cement. In other words, seal any cracks or joints that may allow water entry.
Consider the effects of temperature changes and thermal expansion on high temperature refractory cement structures. Therefore, it provides expansion joints or accommodates thermal movement to prevent cracking or structural damage.
