| Abstract |
| Hydraulic activities and high temperature strength retaining capacities of high
alumina cements containing different amounts of Si02 , Fe20 3 and Ti02 were
studied. It was found that hydraulic properties are not much affected if Si02
content is within 15% but the cements had quick setting and slow hardening
tendency when Si02 content is more than 5%: presence of Fe20 3 to the extent of
5% remarkably improves the hydraulic properties but further addition deteriorates
the hydraulic properties. Ti02 content to the extent of 5% did not alter
the hydraulic properties appreciably. High temperature strength retaining capacities
of high alumina cements are lowered by the presence of both Si0 2 and Ti0 2
and improved by the presence of Fe20 3 • More than 5% Si02 content is undesirable.
Fe20 3 may he present upto 15% but for better performance the amount should not
exceed 5%. |
