Composition of cement Penn State EngineeringCement Manufacturing Process Phases Flow Chart

This is a fluxing agent which reduces the melting temperature of the raw materials in the kiln from 3 000 o F to 2 600 o F It hydrates rapidly but does not contribute much to strength of the cement pasteRaw materials are extracted from the quarry and by means of conveyor belt material is transported to the cement plant There are also various other raw materials used for cement manufacturing For example shale fly ash mill scale and bauxite
