aluminate refractory cement

aluminate refractory cement 1). High strength, compressive strength can reach 80-90MPa 2).Rapid hardening.

aluminate refractory cement CA-50-G9

    CA50-G9 is a type of high strength high alumina cement.Its 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.

1. Features: 1).Main phase is CA2).Rapid hardening and early strength3).Better setting time due to suitable mineral composition.Initial setting time is prolonged and final setting time is shortened.The shortened interval provides enough working time and reduces the maintaining time.4).Its capability and strength are more advanced than other aluminate cements.2.Quality:

high alumina cement  manufactured by sintered method in rotary kiln are according with up-to-date standard GB201-2000,which are graded as G6,G7.Other new products super-early-strength type CA50-N and high-strength type CA50-G9 are to be introduced in addition,whose quality standard are based on CA50 OF GB201-2000.
