Oxygen : Used in the cement industry to improve the combustion efficiency of fuels in kilns, which reduces fuel consumption and greenhouse gas emissions.
Nitrogen : Used for inerting purposes, such as in the purging and blanketing of silos and cement mills, to prevent the risk of combustion and explosion.
Carbon dioxide : Used in the cement industry for pH control in wastewater treatment, as well as in the production of concrete products, where it is used as a curing agent.
