Refractory concrete (cement) SBS SOLUT Cast 85

Product description

Advantages of two-component concretes, where in addition to refractory aggregate, the second component is an orthophosphoric acid based chemical binder are a shorter time for putting the lining into operation.

In turn, these two-component concretes have a number of significant drawbacks, the main of which are the phosphoric acid and its water-soluble salts impact on the human body, as well as on the environment both in the course of working with these components and in the case of containers disposal in which this acid is supplied together with the refractory aggregate.

Another drawback the consumers should pay attention to is titanium and silicon oxides presence in the composition. During long-term contact with liquid aluminum, these two components of the filler are reduced to metal with subsequent secondary oxidation, which leads to the working layer of the lining destruction and an increase of harmful non-metallic inclusions in the aluminum melt.

In addition, the concrete on a chemical binder drying and heating mode requires very strict adherence to the heat treatment schedule and, in fact, averages no more than 70 degrees per hour.

We have developed SBS SOLUT Cast 85 – a special type of refractory concrete resistant both to non-ferrous and ferrous metals melts and to liquid slags formed in the process of metal production. This concrete has all the positive qualities of both two-component concretes on a chemical binder and concretes on a hydraulic binder.


  • The application temperature is in a very wide range: from 300 to 1900 °C
  • The setting time of concrete can be set from 20 minutes to 1.5 hours at the customer’s request
  • The minimum time to remove the formwork is 5 hours
  • The average heating rate of the lining before commissioning is 1000 °C
  • The concrete has a unique heat resistance and can withstand more than 50 water heat exchangers 1300 °С – water
  • The absence of silicon oxide and low-melting compounds in the composition ensures the appearance of a liquid phase only at temperatures above 1700 °C  
  • During the formation of the concrete structure during operation, diffusion sintering prevails, which ensures high mechanical strength at both low and high temperatures
  • The shelf life of this concrete is up to 12 months
  • Concrete can be delivered in any container agreed with customers
