Post Reply WebbHigh alumina cement is slow setting cement. Its initial setting time is 4 to 5 hours and final setting time about 30 minutes later after initial setting. The setting time of high alumina cement is greatly affected by the addition of plaster of paris, lime, Portland cement, and organic matter. Thus no additives should be used.
