Refractory Material--------High Alumina Cement (Alumina Cement)

High Alumina Cement CA50-G9

 

CA50-G9 is a type of high strength aluminate cement,it is production requires raw materials of high quality which must be well selected in order to reduce the impurities.After calcined in rotary kilns with perfect control of the temperature,the strength of CA50-G9 is nearly doubled of that of CA50-G5,that is,the compressive strength(3 day)of CA50-G9 reaches to 85-95 MPa or even higher.other physical characters are also improved.the quality is as good as that of overseas products or even better while the price is much lower.

we have been producing CA50-G9 aluminate cement in large scale with steady quality for both domestic and foreign markets and win praises of the buyers.
