Cement free refractory concretes

REYMA-Reotix has been developing since 2000 a range of thixotropic refractory materials based on SOL-GEL technology, which eliminates the use of aluminous cement as a binder in the refractory concrete and consequently the use of water in the mixture is removed. Instead, a basic bonding liquid (silica colloidal solution) with refractory properties is used.

These types of materials are ideal to use in non-controlled or fast drying areas due to the urgency of the repair, as well as in contact with molten metals, of both ferric and non-ferric nature. The SOL-GEL System forms a chemical – ceramic bonding, less sensitive to heating up speed, forming a more flexible three-dimensional network structure, achieving higher refractoriness.
