CALCIUM ALUMINATE CEMENT CA-60 is a manufactured from raw materials which are high quality limestone and bauxite.The raw materials is to be mixed according to siutable ratio and then to be heated to partly-fused clinker in the rotary kiln.After cooling,the cement clinkers are ground to cement.The content of Al2O3 is cotrolled in 58~62%.The principal compround in the cement is CA2 and CA.It has higher refractoriness,The refractoriness of pure cement paste can be reach 1500°C.
APPLICATION:It is widely used for making various furnaces and high temperature equipments in metallurgical industry,chemical industry,petrolic industry,electrical industry.It is specially used for making bulk refractory materials.
Features:
1.has passed ISO certification
2.has high strength
3.can be harden quickly
4.has erision-resistance
5.high refractoriness
