Cement Manufacturing Process: What is Cement made of

They are called cement rocks because they can be used as a single raw material for the cement manufacturing process 3 Gypsum: It is generally added in very small amounts (about 2% by weight) to the burnt cement (called Clinker) after it is taken out from the kiln and before it is sent for grinding Gypsum is a sedimentary rock having a composition of calcium sulfate (Ca SO 4 2 H 2 O) It is

Raw material preparation From the quarry to raw meal

The purpose of optimum raw material preparation for the cement manufacturing process is to supply the downstream burning process with a raw meal whose quality and homogeneity assures the economi cal production of highquality cements This can only be achieved if the plant designers have precise knowledge of the materials that will be used (raw materials and fuels) This is the basis for

ALTERNATIVE RAW MATERIAL SOURCES FOR CEMENT

It therefore becomes imperative to bring down the cost of cement by investigating into alternative source of raw material for cement production and hence this project From literature, rice husk ash, Ukpo day,& Nsu day contain the basic mineral constituents which limestone has Rice husk was burnt temperatures of 5000c, 6000c, 7000c, and 8000c The best ash was obtained at a temperature of
