In constant efforts to intensify customer service and improve products, Refratechnik Cement have developed innovative refractory concrete grades. These low cement castables (LCC) are state of the art products in refractory technology and meet all the demands of processing and service life.
In order to achieve a good service life, even under the harshest conditions, it is most essential that the castables be installed correctly. Our supervisors are on hand to provide technical assistance and supervision during installation.
The castables are produced in our plants in Gornal/Spain and Zibo/China, and production is subject to the strict demands of DIN EN ISO 9001 and 14001.

The product range includes the following grades:
• conventional concretes
• low cement refractory concretes (LCC)
• free-flowing, low cement refractory concretes
• dry-gunning concretes
• wet-gunning concretes
• pre-cast, monolithic blocks
