History of Kerneos in refractories

A colourful tapestry of calcium aluminates in refractory applications has developed since the first patent (CIMENT FONDU®, 1908) was registered.


History shows that production of calcium aluminates expanded rapidly in 1913 in Europe as the heat resistant properties of calcium aluminates were discovered. Kerneos products were also there when the monolithic refractory castables started to develop in the 1920s.

It was the industrial production of CAC that gave birth to refractory castables. The close association between supplier and user continued with the development by Kerneos of calcium aluminate cement with high alumina content.

This allowed refractory castables to reach new heights of temperature resistance, which in turn stimulated the growth of high temperature refractory castables able to substitute for traditional brick solutions.Today, as was the case over 80 years ago, Kerneos’ aluminate binder systems remain at the heart of monolithic refractory applications and technologies as a key raw material. Calcium aluminates have evolved from high cement conventional formulations to the era of low cement (LC), medium cement (MC) and ultra low cement (ULC) dense castables offering a high refractory performance.

The late 1980s and 90s saw the emergence of new installation technologies. The first of these was low cement refractory castables that could be placed by pumping and / or self-flowing techniques. This was followed by the era of wet gunning or shotecreting. The development of Kerneos calcium aluminates has been intimately interwoven with the technological evolution of these refractory castables and products have been continually improved to meet the ever more stringent requirement of these applications.

Capitalizing on this rich and diverse history, Kerneos continues to deploy its strategy to better serve the customer requirements and to accompany the technological evolution.
