Cement is everywhere, but few notice the impact it has on the environment. A standard building material used everywhere, it is often confused with concrete.Cement is a key component in making concrete. By burning limestone at extremely high temperatures, this process turns the stone into a fine powder that's then mixed with clay and other minerals.

All over the world, cement is one of the most important building materials. Whether for houses, bridges or tunnels, we cannot imagine our modern world without it. Join us for a short tour to experience how cement is made: starting with the extraction of raw materials and ending with the finished product.

The production of cement is a two-step process that involves producing a clinker from raw materials (mainly limestone and clay) that is heated within a kiln at an intense heat, before being cooled at 100 o C – 200 o C. In a second step, gypsum and sometimes additions like coal fly ash are added to the clinker and ground to a fine cement powder.

Cement kilns are used for the pyroprocessing stage of manufacture of Portland and other types of hydraulic cement, in which calcium carbonate reacts with silica-bearing minerals to form a mixture of calcium silicates.Over a billion tonnes of cement are made per year, and cement kilns are the heart of this production process: their capacity usually defines the capacity of the cement plant.

Cement and global warming • Making cement results in high levels of CO 2 output. • Cement production is the third ranking producer of anthropogenic (man-made) CO 2 in the world after transport and energy generation. • 4 - 5% of the worldwide total of CO 2 emissions is caused by cement production. • CO 2 is produced at two points during cement production :

• Chalk is porous and often has high moisture content that leads it to its use in the 'semi-dry/wet' manufacturing process of making cement. This particular process represents some 16% of total production. Shale • Shale is a pure sedimentary rock made of very fine silt, clay and quarz. Shale falls in the category of mudstones.

If the cement industry were a country, it would be the third largest emitter in the world. In 2015, it generated around 2.8bn tonnes of CO2, equivalent to 8% of the global total – a greater share than any country other than China or the US.. Cement use is set to rise as global urbanisation and economic development increases demand for new buildings and infrastructure.

Cement production is currently the largest single industrial emitter of CO2, accounting for ∼8% (2.8 Gtons/y) of global CO2 emissions. Deep decarbonization of cement manufacturing will require remediation of both the CO2 emissions due to the decomposition of CaCO3 to CaO and that due to combustion of fossil fuels (primarily coal) in calcining (∼900 °C) and sintering (∼1,450 °C).
