CEMENT RAW MATERIALS - International Cement Review

2013-6-9  The quality of cement clinker is directly related to the chemistry of the raw materials used. Around 80–90% of raw material for the kiln feed is limestone. Clayey raw material accounts for between 10–15%, although the precise amounts will vary. Magnesium carbonate, which may be present in limestone, is the main undesirable impurity. The level

Investigation of Raw Material for the Manufacturing of ...

2014-9-5  Limestone is a valuable raw material, which is widely used in the chemical, metallurgical and construction industries throughout the world. With huge deposits of limestone in Pakistan, it is immensely used as the major raw material in cement manufacturing. Limestone has two most important major groups; organic, chemical and detrital or clastic. Many of the commonly occurring limestones contain organic and chemically precipitated material in varying proportions. Limestone is one of the raw materials used for cement manufacturing. In addition to other raw material such as chalk, clay, marl and shale, limestone

Raw Material Substitution - Cembureau

The main raw material used in cement production has traditionally been limestone. Limestone is abundantly available, but over 60% of the industry’s CO 2 emissions are caused by transformation of limestone into lime, called “decarbonation”. Accordingly, part of the route towards a low carbon concrete-built environment can involve limestone substitution.
