| Abstract |
| Two calcium aluminate cements comprising predominantly of CaO.Al20 3 and
Ca0.2Al20 3 respectively were prepared by sintering process. These cements were
used in different proportions along with Assam sillimanite, calcined kyanite and
calcined Kashmir bauxite as refractory castables. The physical and refractory properties
such as apparent porosity, bulk density, modulus of rupture, refractoriness underload,
PCE, spalling resistance and also modulus of rupture and linear change after firing
to different temperatures were determined.
Castables with kyanite as aggregate material had the best refractory properties.
The refractoriness of the castables was adversely affected due to the presence of titania
in the aggregate materials. |
