High Alumina Cement

HIGH ALUMINA CEMENT

These are calcium aluminate cement binders produced by sintering method from a mixture of aluminous and calcareous materials. These products is used for making refractory castables after proportioning with selected refractory aggregates in various combinations to get specific high-temperature properties. These products set hydraulically. We at Mahakoshal Refractories Pvt. Ltd., are manufacturers and sellers of various types of High Alumina Cement.

Our industry experience of past 5 decades, have enabled us to study and produce the best possible High Alumina Cement at a very cost-effective price.

For storage – The period indicated begins with the date of production and is based on the storage under cool, dry, frost-free conditions.  If the period is exceeded, the material does not necessarily become unworkable.  Yet in this case, it is recommended that material is tested prior to use.  Other than the above storage conditions may affect the storage life of the material.
