Product Description
Calcium Aluminate Cemet Fused CA50:
Our Calcium Aluminate Cements CA-50 series 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.
Alumina content 50%-55%
High early strength, fast setting and hardening. 24hours strength can reach 70% the ultimate strength.
The high heat of hydration, the hydration heat concentration
The high heat of hydration with exothermic concentration
The frost resistance is good, normal hardening can also in the lower temperature environment
Chemical erosion and anti-bio at wide range, especially strong anti sulfate erosion.
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.
Mainly used in formulating monolithic refractory and widely in steel, crude oil, electrical, nonferrous metal, construction and kiln industries.
CA50F :
★ Usually used as refractory binders in boiler
★ High heat of hydration with exothermic concentration
★ Good workability, high construction efficiency
★ Mainly applicable to general industrial and civil boiler temperature below 1300 ºC
CA50R
★ Selected high-quality raw materials, special formula, resistance to high temperature performance between A700 and A900
★ Normal condensation, excellent construction performance and early strength development is extremely fast,above the 6h compressive strength up to 30MPa, can greatly improve the construction speed of casting material;
★ Stronger adaptability to the environmental temperature changes, in the low temperature environment in winter can still maintain the strength development faster and earlier release time;
★ Especially suitable for winter construction, repair and other occasions requiring fast demoulding curing
We can offer high alumina cement with different fineness as per the customers' requirements.

Notes:
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.
Mixing water PH should be around 7.
Alkali project can't be applied in.
Water reducing agent must be tested before using
Pay attention to Aggregate and powder material's particle size and chemical content and impurities ,Fe, S, Alkali, Cl-, should also be specially noted.
Do not mixed with other raw material when transported.
