Cement production and the chemistry

The Chemistry and Production of Bone Cement. These days, damaged joints are frequently replaced with artificial parts in a surgical procedure known as arthroplasty. When this is done the space between the artificial parts and the bone this is filled with bone cement. This lesson describes how this cement is the result of a polymerisation

    Cement production is responsible for around 7% of worldwide greenhouse gas emissions. The only larger contributors are electricity generation and transport. Most of the CO 2 released when cement is made comes from the chemical reaction. The limestone from which it is made is calcium carbonate, and when this is heated it gives off carbon dioxide, and forms calcium oxide
