Product Description

Aluminate cement also named high alumina cement, caclium aluminate cement, refractory cement .
Our refractory cement divide into normal grade and high strenght grade aluminate cement.
Normal grade aluminate cement is widely used in refractory castable, gun-mix refractory etc unshaded refractory materials,shuc as refractory castable for boiler wall,beam.
Normal grade aluminate cement data as follows:

	Fe2O3		≤2.5	≤2.5	≤2.0
	R2O		≤0.4	≤0.4	≤0.4
Main crystal phase			CA
Secondary phase			CA2,C12A7,C2AS,CT
Residue after 325Mesh(%)			≤15
Blaine  (m^2/kg)			≥300
Initial setting time(min)			≥30
Final setting time(h)			≤6
Flexural strength (Mpa)		1d	5.5	6	6.5
		3d	6.5	7	7.5
Compressive Strength (Mpa)		1d	40	45	50
		3d	50	55	60

Packing of our aluminate cement:
25kg/50kg/1000kg woven water proof bags, or as per customers' request
High strength aluminate cement is widely used as binder in special unshaped refractory materials which has demands of early and high strength,such as refractory castable for CFB cyclone tube.
High strenght refractory cement data as follows:
