High Alumina Cement: Manufacture and Properties | Concrete Technology

The high alumina cement is black in colour and its rate of strength development is very high. About 80% of its ultimate strength is developed at the age of 24 hours Even 8 hours strength is sufficient for the removal of the form work. The high rate of gain of strength is due to its rapid hydration. Its rate of heat develop­ment also is very high.
