International Materials Reviews, 2001
Castable refractories containing calcium aluminate cement (CAC) are used ubiquitously in a range of furnace lining applications in the iron and steel, cement, glass, ceramic, and petrochemical industries. This review outlines their development from conventional high cement materials, through low cement and ultra-low cement castables to the present ...

Nano-bonded refractory castables
Ceramics International, 2013Abstract Calcium aluminate cement (CAC) contents higher than 3 wt% in refractory castables can have some drawbacks in the various processing steps (mainly drying) and also in their refractoriness when in contact with SiO 2 . The use of colloidal silica as an alternative binder has been studied by many researchers in recent years and recently reports ...

Castable Refractories Based on Zircon
Transactions of the Indian Ceramic Society, 1971Castables based on zircon sand were made and their physical properties were determined after various heat treatments. It was found that zircon sand can be used as an aggregate material in castables with good results.

Silicon carbide refractory castables
Refractories and Industrial Ceramics, 2005Optimum formulations for castables intended for different service conditions are proposed. Silicon carbide castables containing ultradisperse particles of cement, silica fume, and electrofused corundum are developed. The castables do not weaken on heating and display superior operational properties: the compressive strength is 40–80 MPa at sintering ...

Thermal Conductivity of Refractory Castables
Journal of the American Ceramic Society, 1963Thermal conductivity measurements were made on various refractory castabales of both dense fireclay and high‐alumina types as well as on several insulating castables. These tests, covering mean specimen temperatures of 200° to 2000°F, indicated how the thermal conductivity of a castable material varies with thermal history.
