| High alumina cement |
This cement has a very high rate of strength development. In this type of cement, up to 80% of total strength is achieved in one day only. Lime and bauxite are used as raw material for producing this cement. Because of large proportion of bauxite, this cement is called high alumina cement. The rate of heat generation is also proportionately high i.e. 2.5 to 3 times of rapid hardening cement. The form work should be stripped-off as early as possible to prevent built-up of high temperature.
This cement is resistant to sulphate attack due to inert quality of alumina gel and absence of Ca(OH)2.
