This exploitation of materials consists of using by-products from other industries in addition to limestone and clay For example it is possible to use fly ash from thermal power plants This exploitation of materials is carried out in a rigorous manner a professional charter has been drawn up and procedures that apply to all cement factories have been developed for the acceptance of new
Common materials used to manufacture cement 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 that is ground into the fine powder that we commonly think of as cement
The conservation of natural resources is part of our sustainable business strategy That is why we make greater use of waste materials and by-products from other industries as valuable raw materials and fuels We use alternative raw materials for the production of clinker which is the most important intermediate product in the manufacture of cement In this way we reduce the amount of CO2
Sixty tons of industrial side streams can be used as raw material To move society toward a circular economy and reduce society's use of raw materials industry by-products (side streams) have to be treated as products as well This has been the objective in the Min-Pet project (2016–2019) where the use of a mineral side stream Petrit-T has been upscaled as a raw material for

cement is the production of concrete formed by mixing it with gravel sand and water The major pathway for mercury releases from the cement industry is via emissions to the atmosphere in which mercury that is present in the raw materials (e g limestone
2016/9/22If the cement is too fine its shrinkage is large in the hardening process Thus the finer the cement is ground the more energy will lose and the higher the cost will be Usually the grain size of the cement particles is within 7-200pm (0 007-0 2mm) (4)
