Compositions, technology features, and the main properties of cement-free refractory concretes (CFRC) based on a silica-sol binder are considered. Concretes of high-alumina and corundum compositions of CFRC, as well as in the Al2O3–SiO2–SiC–C system predominate in this group. Improved thermal and thermomechanical properties of CFRC compared with the properties of LCRC are largely due to mullitization as a result of interaction of nanodispersed SiO2 (silica sol and microsilica) with reactive alumina of the matrix system. Extensive and effective use of CFRC based on silica binders is achieved in blast furnace production (chutes, cold and hot shotcreted blast furnace shafts) and for lining cement production furnaces.
