Common raw materials used to make the powder include limestone, shells, and chalk or marl combined with shale, clay, slate, blast furnace slag, silica sand, and iron ore. These ingredients, when heated at high temperatures form a rock-like substance called clinker that is ground into the fine powder that we call cement.

Another option may be to replace the problematic raw material with a finer, easier-to-grind and/or easier-to-burn alternative. Limiting the use of correctives like quartz sand and burning the clinker at a marginally lower silica modulus may also be helpful, especially when combined with some fine-tuning of the alumina modulus.

Chemical analysis showed that the mudstone raw material is very rich in calcium and silica. In this respect, It has a more stable structure than other cement raw materials. Therefore, the cement produced with clay stone requires the use of various regulatory raw materials and thus creates additional costs.
