Cement clinker is a material generated at liquefaction stage when clay and limestone are heated in the rotary kiln at temperature between 1400Â°C-1500Â°C. Our company, Manali Construction makes available, white and grey cement clinkers for purchase. These appear in lump form and their size varies, from 3mm to 25mm. The lumps can be ground into fine powder by the cement manufacturers. This fine powder can be blended with gypsum for making cement. This material acts as a binder. Ferrite, aluminate, belite and alite are the major components of cement clinker. When not in use, this material can be stored in dry condition for long. Our company supplies this material to cement manufacturers in areas where cement raw material are scarce.
