Abstract
The present invention relates to a dry refractory particulate composition comprising a zeolithic microstructure, to a green body and to a refractory lining formed therefrom, and to uses thereof.
Claims22
A dry refractory particulate composition comprising:
- 5% to 95% by weight of aggregate,
- 1% to 8% by weight of silica fume,
- 0.1% to 1.5% by weight of hydratable alumina,
- 0.1% to 1% by weight of a calcium source, and
- 0.01% to 1% by weight of dispersant,
- wherein the calcium oxide content is no greater than 0.3% by weight and all percentages by weight are based on the total dry weight of the dry refractory composition.
