Raw material for cement Minerals of natural origin as well as industrial products can be used for the production of cement. Starting materials for this purpose are mineral compounds, containing the main components of cement, lime, silica, alumina, and iron oxide. The two main components are generally limestone and clay. In cement raw materials.
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

Introduction. Sand and gravel are used extensively in construction. In the preparation of concrete, for each tonne of cement, the building industry needs about six to seven times more tonnes of sand and gravel (USGS, 2013b). Thus, the world's use of aggregates for concrete can be estimated at billion to billion tonnes a year for 2012 alone.

Since a form of calcium carbonate, usually limestone, is the predominant raw material, most plants are situated near a limestone quarry or receive this material from a source via inexpensive transportation. Cement manufacturing begins with quarrying operations in which limestone in mines is quarried and brought to crusher for crushing.
China's increasing appetite for raw materials and its dearth of domestic resources in certain minerals make it increasingly dependent on raw material imports. To shore up the security of its resource supply lines, Beijing has started to build strategic alliances with countries throughout Africa (Alden, 2005; French, 2007; Large, 2007; Mwega ...
View the interactive animation of the cement production process to learn how cement is made by CEMEX. 1. Mining the raw material. Limestone and clay are blasted from rock quarries by boring the rock and setting off explosives with a negligible impact of the environment, due to the modern technology employed. 2. Transporting the raw material.
