Cement is used in construction to bind other materials together. It is mixed with sand, gravel and water to produce concrete, the most widely used construction material in the world. Over 10bn tonnes of concrete are used each year. The industry standard is a type called Portland cement.

Concrete is a mixture of aggregates and paste. The aggregates are sand and gravel or crushed stone; the paste is water and portland cement. Cement comprises from 10 to 15 percent of the concrete mix, by volume. Through a process called hydration, the cement and water harden and bind the aggregates into a rocklike mass.

In the US, portland cement production accounts for about 0.33% of the annual energy consumed, which is equivalent to the amount of energy in around 13 million tons of coal. It is also true that cement has a lower embodied energy (the sum of all the energy required to produce something) than materials such as steel or aluminium, meaning that it’s not a simple solution of changing to another

Cement production also is a key source of CO2 emissions, due in part to the significant reliance on coal and petroleum coke to fuel the kilns for clinker production. Globally, CO2 emissions from cement production were estimated at 829 MMTCO2 in 2000 7, approximately 3.4% of global CO 2 emissions from fossil fuel combustion and cement production.

Cement production is one of the largest industries in the world. Annual world production in 2013 was approximately 4 GT (of which, about half was in China). It is produced in kilns at around 1400o C (2500 o F), and approximately 750 kg (1650 lb) of CO 2 are released for each tonne (2205 lb.) that is made.
