Use of high alumina cement (HAC) as low cement castables (LCC) and ultra-cement castables (ULCC) has increased for refractories applications over the last few years. HAC is being prepared commercially, by fusing or sintering a mixture of argillaceous and calcareous materials above 1500°C and subsequent grinding to obtain a fine powder.
What is Healthy Cement?
What is Healthy Cement? Cement is a finely ground organic hydraulic binder which when mixed with water forms a paste that sets and hardens through a hydraulic reaction. Better the quality of cement, stronger the setting and ultimately a more durable structure. Thus, quality of cement is of supreme importance in any kind construction.

Desired cementing phases CA, CA 2, and CA 6 were formed at a very low temperature. One advantage of this process is to exclude silicate phases which are the cause behind eutectic formations in such cements. These silicate phases if any, decrease the refractoriness and the cement is not suitable for high temperatures.

Cement Manufacturing Process: How the Cement is Made?
3. Grinding: The clinkers as obtained from the rotary kiln are finely ground in ball mills and tube mills. During grinding, a small quantity, about 3 to 4 per cent, of gypsum is added. The gypsum controls the initial setting time of cement. If gypsum is not added, the cement would set as soon as water is added.
