Plaster, lime and cement
CPC v2.1 Code: 374
About plaster, lime and cement
cpc code 374 covers the production of plaster, lime, and cement - essential materials for the construction industry. These products play a crucial role in the built environment, providing the foundation for buildings, infrastructure, and a wide range of other applications. The plaster, lime, and cement industry is a significant contributor to the broader economy, supporting various downstream sectors and enabling the development of modern societies.
Production process
The production of plaster, lime, and cement involves several key steps. Plaster is typically made by heating gypsum to remove water, then grinding the resulting material into a fine powder. Lime is produced by heating limestone (calcium carbonate) to high temperatures, driving off carbon dioxide and leaving behind calcium oxide. Cement, on the other hand, is manufactured by grinding and heating a mixture of limestone, clay, and other materials to create a binding agent.
Production inputs
The main inputs for the plaster, lime, and cement industry include raw materials such as gypsum, limestone, and clay. Additionally, the industry requires specialized equipment and machinery for mining, processing, and transportation. Energy sources, such as natural gas or electricity, are also crucial for the high-temperature processes involved in production.
Production outputs
The primary outputs of the plaster, lime, and cement industry are the finished products themselves, which are then consumed by various other industries. Plaster is used in construction for wall and ceiling finishes, while lime is used in a wide range of applications, including 375 Manufacture of other chemical products, 41 Construction of buildings, and 42 Civil engineering. Cement is a key ingredient in the production of concrete, which is essential for 41 Construction of buildings and 42 Civil engineering.
