Cement clinkers

CPC v2.1 Code: 3743

About cement clinkers

cpc code 3743 covers cement clinkers, a critical raw material in the production of cement. Cement is a fundamental building material used in construction projects worldwide, making the cement clinker industry a vital component of the broader construction and infrastructure sectors. As a key input for cement manufacturing, cement clinkers play a crucial role in the global economy, supporting the development of residential, commercial, and industrial facilities.

Production process

Cement clinkers are produced through a multi-step process that involves the calcination of limestone and other raw materials in a kiln at high temperatures, typically around 1,450°C. This process drives off carbon dioxide, leaving behind a partially fused material known as cement clinker. The clinker is then ground and mixed with other additives to produce the final cement product.

Production inputs

The main inputs required for the production of cement clinkers include limestone, clay, shale, and other mineral resources. Additionally, the industry relies on specialized machinery and equipment, such as rotary kilns, grinding mills, and material handling systems. Energy, in the form of fuel for the high-temperature kilns, is another critical input for the cement clinker manufacturing process.

Production outputs

The primary output of the cement clinker industry is, of course, cement clinkers, which are then used by 3744 Cement manufacturers to produce various types of cement. These cement products are then consumed by a wide range of industries, including 4200 Construction, 4210 Building construction, and 4220 Heavy and civil engineering construction.
