Manufacture of cement

NACE v2.1 Code: C23.51

About manufacture of cement

NACE code 23.51 covers the manufacture of cement, a vital construction material that is essential for the development of infrastructure, buildings, and other structures. The cement industry plays a crucial role in the broader economy, providing the foundation for numerous downstream industries and contributing to economic growth and development.

Production process

The production of cement involves a multi-step process. The primary raw materials, such as limestone, clay, and other minerals, are extracted and then crushed, ground, and blended to create the cement mixture. This mixture is then heated in a kiln at high temperatures, typically around 1,450°C, to produce clinker. The clinker is then ground with gypsum and other additives to create the final cement product.

Production inputs

The cement industry requires a range of raw materials, including limestone, clay, sand, and other minerals. Additionally, the industry relies on specialized machinery and equipment, such as crushers, mills, kilns, and packaging systems. Energy, in the form of electricity and fuel, is another significant input for the cement manufacturing process.

Production outputs

The primary output of the cement industry is the cement product, which is then used by various 41.20 Construction of residential and non-residential buildings, 42.11 Construction of roads and motorways, 42.13 Construction of bridges and tunnels, and other construction-related NACE codes to build infrastructure, buildings, and other structures.
