The most common raw rock types used in cement production are Limestone (supplies the bulk of the lime) Clay, marl or shale (supplies the bulk of the silica, alumina and ferric oxide) Other supplementary materials such as sand, fly ash/pulverised fuel ash (PFA), or ironstone to achieve the desired bulk composition.
There are four stages in the manufacture of portland cement (1) crushing and grinding the raw materials, (2) blending the materials in the correct proportions, (3) burning the prepared mix in a kiln, and (4) grinding the burned product, known as clinker , together with some 5 percent of gypsum (to control the time of set of the cement).
Blasting is not required for quarrying of chalk, and the crushing process can also be omitted which will reduce considerably cement production cost. Marls Limestone with admixtures of silica, clay substance and iron oxide are called marls.
The quality of cement clinker is directly related to the chemistry of the raw materials used. Around 8090% of raw material for the kiln feed is limestone. Clayey raw material accounts for between 1015%, although the precise amounts will vary. Magnesium carbonate, which may be present in limestone, is the main undesirable impurity. The level
