Castables

Castable Refractories are predominantly dry, granular refractory mixtures designed to be mixed on site with water and capable of curing to a stable dimensional form through hydraulic or chemical setting.

Castable refractories are particularly suited to the molding of special shapes and parts at the installation site. They can be used for forming complete furnace linings and other unique shapes.

Castables have the advantage of being readily usable at the operating temperature of the equipment after hydraulic or chemical setting and moisture removal have taken place.

Our products are best used in industries such as Chemicals, Metal Foundries, Cement, Fertilizers, Ceramics, Oil refineries, Petrochemicals, Textile Plants and Paper industries.

From insulating to dense products, Asfour MR. can supply a full line of castable refractories and no cement castables utilizing various bonding systems.


We can customize our Castable Refractories to our clients' specifications and requirements. Our typical Castables include but are not limited to:


  • Alumina Silicate Castables
  • Low Cement Castables
  • Light Weight Castables
  • Cordierite Castable

Lightweight Castables

This type of refractory material contains refractory aggregates, refractory powder, binders and other additives. Key features include low viscosity, Casting and Vibration molding options, and direct or fluid-mix application

Lightweight castables are primarily used as insulating backup linings. However, they can also be used as working linings in non contact areas such as roofs.
