Building with Fire in Mind: Refractory Cement vs. Furnace Cement

When it comes to constructing structures that endure extreme heat and the test of time, making the right choice of cement is crucial. In the world of high-temperature applications, two types of cement often come into play: refractory cement and furnace cement. In this blog, we'll explore the differences between these two materials, their key features, and why Oreworld is a brand you can trust for all your refractory needs.

Refractory Cement vs. Furnace Cement: Understanding the Basics

Refractory Cement

Refractory cement, also known as refractory castable, is a specialized cement designed to withstand high temperatures without deforming or breaking down. It is engineered for use in applications where temperatures can reach up to 2500°F (1371°C) and is commonly used in industries such as metallurgy, foundries, and kiln manufacturing. Refractory cement is a go-to choice for lining the interiors of furnaces, kilns, and ovens due to its exceptional heat resistance.

Furnace Cement

Furnace cement, on the other hand, is a type of cement that is primarily used for sealing joints and repairing small cracks in appliances like stoves, fireplaces, and furnaces. It has a lower heat resistance compared to refractory cement and is not intended for applications where prolonged exposure to extremely high temperatures is required.

Key Differences Between Refractory Cement and Furnace Cement

Heat Tolerance

The most significant difference between the two is their ability to withstand heat. Refractory cement can handle temperatures well above what furnace cement can endure. It maintains its structural integrity and strength under extreme heat, making it ideal for high-temperature environments.


Refractory cement is used for creating linings in high-temperature industrial equipment, while furnace cement is more suitable for repairing and sealing small cracks or gaps in household heating appliances.


The composition of these cements also differs. Refractory cement typically contains a blend of high-alumina and calcium-aluminate materials, enhancing its heat resistance. Furnace cement, on the other hand, often contains a mix of fireclay and silica.
