calcium aluminate cement quality same to secar 80 secar 71 high alumina refractory cement
High alumina cement, also known as HAC, is a special cement compound that develops strength very quickly. It is produced much in the same way as other forms of cement, but its unique makeup results in characteristics that are unique to HAC. Specifically, high alumina cement is chemical resistant and can withstand frigid temperatures.
High alumina cement are calcined by natural high grade bauxite and limestone as selected raw material. The main phase of this series is CA and CA2 which mainly formed the clinker. After grinded to the best particle size distribution, the cements will meet the demand of the most critical customers.
High alumina cement Properties:
1.High Almina Content
2.High early strength, fast setting and hardening. 24hours strength can reach 70% the ultimate strength.
3.The high heat of hydration, the hydration heat concentration
4.The high heat of hydration with exothermic concentration
5.The frost resistance is good, normal hardening can also in the lower temperature environment
6.Chemical erosion and anti-bio at wide range, especially strong anti sulfate erosion.
7.Ideal for high temperature and thermal shock resistance performance is very admirable , its refractory temperature can reach 1370 ºC. 1500 ºC. can be reached if better refractory aggregate were chosen.
8.Mainly used in formulating monolithic refractory and widely in steel, crude oil, electrical, nonferrous metal, construction and kiln indust
1)Particle size can be customized
2)Chemical and physical index can be customized
3) Testing methods of S, Cl- can be acquired if customer need.

High Aluminum Cement Notes:
1.In the construction process, in order to control condensation time, mixed with Portland cements, limestone or any other raw material can produce Calcium hydroxide is strictly forbidden. Tools and equipment must be washed clean before using.
2.Mixing water PH should be around 7.
3.Alkali project can't be applied in.
4.Water reducing agent must be tested before using
5.Pay attention to Aggregate and powder material's particle size and chemical content and impurities ,Fe, S, Alkali, Cl-, should also be specially noted.
6.Do not mixed with other raw material when transported.
