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.
