| Abstract |
| Bauxite is an important raw material for the production of highalumina
cements. Purer grade bauxites are mainly used for industries
like aluminium, alum, etc. Use of low grade bauxites increases the
titania content of high-alumina cements to an unusual extent.
High-alumina cements containing varying amounts of titania were
prepared from analytical grade chemicals and the phases were identified
by X-ray measurements. It was found that Ti02 had a beneficial
role in the hydraulic and other related properties of high-alumina
cements up to a certain limit. The suitability of these cements in the
preparation of castables was also studied by measuring high-temperature
strength retaining capacities of the cements using different
aggregates. The maximum allowable limit of titania content may be
suggested to be 4 per cent. |
