Quicklime, slaked lime and hydraulic lime

CPC v2.1 Code: 3742

About quicklime, slaked lime and hydraulic lime

cpc code 3742 covers the production of quicklime, slaked lime, and hydraulic lime. These materials are essential inputs for a wide range of industries, including construction, steel manufacturing, and water treatment. Lime products play a crucial role in the broader economy, enabling the production of essential goods and infrastructure that support economic growth and development.

Production process

The production of quicklime, slaked lime, and hydraulic lime typically involves the thermal decomposition of limestone or other calcareous materials. This process, known as calcination, is carried out in specialized kilns or furnaces. The resulting quicklime is then either left in its raw form or further processed into slaked lime or hydraulic lime, depending on the specific application requirements.

Production inputs

The primary input for this industry is limestone, which is the main raw material used in the production of lime products. Other inputs include fuel sources, such as coal or natural gas, to power the calcination process, as well as water and various additives depending on the desired lime product. Specialized equipment, such as kilns, crushers, and grinding mills, are also essential for the efficient production of lime.

Production outputs

The main outputs of this industry are quicklime, slaked lime, and hydraulic lime. Quicklime is used in a variety of applications, including 2421 Basic chemicals, 2694 Cement, lime and plaster, and 3710 Iron and steel basic industries. Slaked lime is commonly used in 2694 Cement, lime and plaster and water treatment processes. Hydraulic lime is primarily used in the 2694 Cement, lime and plaster industry.
