Raw materials for clinker production are for good reasons primarily based on limestone, clay or its natural mixture, marl. In many cases, alternative raw materials are used mostly as corrective materials. Typical examples are given in Table 1. With respect to resource efficiency along the value chain, concrete recycling is already in an ...

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

The raw meal also contained limestone and corrective materials (bauxite and iron oxide) but marls were not used. The clinker produced contained free lime rates similar to the standard clinker production. Conclusion. Replacement of Portland clinker raw materials by RA is promising but challenging because of the variability in the RA composition.

Cement clinker is a solid material produced in the manufacture of Portland cement as an intermediary product. Clinker occurs as lumps or nodules, usually 3 millimetres (0.12 in) to 25 millimetres (0.98 in) in diameter. It is produced by sintering (fusing together without melting to the point of liquefaction) limestone and aluminosilicate materials such as clay during the cement kiln stage.

What Are The Raw Material Used For Production Of Concrete

Cement is so fine that 1 pound of cement contains 150 billion grains. The cement is now ready for transport to ready-mix concrete companies to be used in a variety of construction projects. Although the dry process is the most modern and popular way to manufacture cement, some kilns in the United States use a wet process.
