Refractory cement is a cementitious refractory material used as part of refractory construction, maintenance, repair and refractory formulation systems. It is designed for applications where ordinary construction cement is not appropriate for the required temperature and service environment.
Industrial refractory cement selection should not be based on temperature alone. The chemical composition of the cement, compatibility with the surrounding refractory material, operating atmosphere, thermal cycling, mechanical exposure and required installation characteristics all need to be considered.
Highland Refractory offers CA50, CA60, CA70 and CA80 grades with different alumina and impurity limits. This grade structure allows buyers to select a refractory cement according to the requirements of the final refractory formulation and industrial application.
Refractory cement is formulated for elevated-temperature service and can form part of refractory systems used in industrial thermal equipment. The appropriate grade should always be selected according to the actual service conditions.
CA50–CA80 grades provide different specified levels of Al2O3, SiO2, Fe2O3, alkali, sulfur and chloride, allowing the product to be matched to refractory formulation requirements.
Cement selection needs to be evaluated together with refractory aggregates, powders and other components used in the complete refractory system.
The available CA grades allow industrial buyers to specify a cement according to project requirements instead of using one general material specification for every application.
Highland Refractory's refractory cement range includes CA50, CA60, CA70 and CA80. The grades are differentiated primarily by alumina content and controlled levels of silica, iron oxide and other specified impurities.
CA50 provides a 50–60% Al2O3 range with controlled SiO2, Fe2O3, alkali, sulfur and chloride limits. It can be selected where a CA50 refractory cement specification is required.
CA60 provides a higher alumina range of 60–68%, together with lower specified SiO2 and Fe2O3 limits compared with CA50.
CA70 is a higher-alumina refractory cement grade with Al2O3 between 68–77%, SiO2 ≤1.0% and Fe2O3 ≤0.7% according to the supplied specification.
CA80 provides Al2O3 at 77% or above, with SiO2 and Fe2O3 each limited to ≤0.5% according to the supplied specification.
The following table provides the available chemical specifications for Highland Refractory CA50, CA60, CA70 and CA80 refractory cement grades. Values are expressed as percentage by weight unless otherwise stated.

A dash (—) indicates that no value was provided for that parameter in the supplied specification table. The final grade specification for a commercial order should be confirmed against the applicable technical data sheet and purchase specification.
Refractory cement can be considered for different industrial thermal systems. The appropriate grade depends on the equipment, operating conditions, refractory substrate and requirements of the complete refractory system.
Refractory cement can be used in selected furnace construction, maintenance and repair applications. Selection should consider the operating temperature, refractory substrate and furnace atmosphere.
Boiler-related refractory applications may involve elevated temperature, thermal cycling and flue-gas exposure. The cement grade should be compatible with the surrounding refractory materials and service conditions.
Refractory cement may be selected for certain kiln-related refractory construction and maintenance requirements where temperature resistance and material compatibility are required.
Foundry equipment can expose refractory systems to high temperatures, thermal cycling and mechanical wear. Material selection should therefore consider the complete service environment.
Selecting the right refractory cement should begin with the requirements of the final refractory system. Industrial buyers should compare the available grade against the chemical, thermal and physical requirements of the application.
Define whether the cement will be used in a furnace, boiler, kiln, foundry or another high-temperature industrial system. This establishes the basic service environment for further evaluation.
Compare the required Al2O3, SiO2, Fe2O3, alkali, sulfur and chloride limits with the available cement grades.
The selected cement should be compatible with the refractory aggregates, powders, bricks or other materials used in the complete formulation or lining system.
Consider operating temperature, thermal cycling, furnace atmosphere, chemical exposure, abrasion and other service conditions that could influence refractory performance.
Before procurement, compare the requested grade and chemical limits with the applicable technical data sheet and project specification.
Buyers looking for a refractory cement supplier should provide enough technical and commercial information to identify the correct grade. A generic product name is usually not sufficient for project-based industrial procurement.
Highland Refractory can review the requirement according to the application, required CA grade, chemical specification, estimated quantity, destination and other project requirements.
Buyers evaluating refractory cement price, refractory cement suppliers, refractory cement manufacturers or wholesale supply can provide these details together with the required quantity and destination for a more accurate quotation.

Refractory cement is a cementitious refractory material designed for high-temperature applications. It can form part of refractory construction, maintenance, repair and refractory formulation systems where ordinary construction cement is not suitable.
Highland Refractory's current grade range includes CA50, CA60, CA70 and CA80. The grades differ mainly in alumina content and specified levels of silica, iron oxide and other controlled components.
The main difference is the chemical composition. Al2O3 increases from the CA50 range through CA80, while the specified SiO2 and Fe2O3 limits become lower in the higher grades.
Refractory cement can be used in selected industrial furnace, boiler, kiln and foundry applications. The correct grade depends on the equipment, operating conditions and the requirements of the complete refractory system.
Start with the application and service conditions, then compare the required chemical composition with the available CA50, CA60, CA70 and CA80 specifications. Compatibility with the surrounding refractory formulation should also be confirmed before procurement.
Submit the intended application, operating conditions, required grade or chemical specification, estimated quantity and delivery destination through the Highland Refractory contact page . These details help determine the applicable product and quotation requirements.
Tell Highland Refractory your application, required CA grade, chemical specification, quantity and delivery destination. The requirement can then be reviewed against the available refractory cement grades and applicable technical documentation.
