HYBRID Technology – Advance for Sol-Gel Bonded Refractory Concrete
Monolithic refractory castables can contain different bonding agents. The commonly used cement and silica sol binders have different advantages for their usage. The cement bonding with calcium aluminate cement is characterised by the development of high strength at a temperature up to 1000 °C. A general disadvantage is, that corresponding linings need to be heated up very sensitive, especially at the initial heat-up.
