Manufacture of cement, lime and plaster

NACE v2.1 Code: C23.5

About manufacture of cement, lime and plaster

NACE code 23.5 covers the manufacture of cement, lime, and plaster - essential materials for the construction industry and broader infrastructure development. This industry plays a vital role in the economy, providing the foundational building blocks for a wide range of construction projects, from residential and commercial buildings to roads, bridges, and other critical public works. The production of these materials is a capital-intensive process that requires significant investment in specialized equipment and facilities.

Production process

The manufacture of cement, lime, and plaster involves a multi-step process. For cement production, the key steps include quarrying and crushing raw materials such as limestone, clay, and gypsum, followed by grinding, blending, and heating the mixture in a kiln to produce clinker. The clinker is then ground with other additives to create the final cement product. Lime production follows a similar process, with the key difference being the use of limestone as the primary raw material. Plaster is typically produced by heating and grinding gypsum, which is then mixed with other additives to create the desired consistency and properties.

Production inputs

The primary raw materials required for this industry are limestone, clay, gypsum, and other mineral resources. Specialized equipment such as crushers, mills, kilns, and packaging machinery are also essential inputs. Additionally, the industry relies on significant energy resources, including electricity and fossil fuels, to power the production process.

Production outputs

The main outputs of this industry are cement, lime, and plaster, which are then consumed by a variety of other NACE codes, including 41.2 Construction of residential and non-residential buildings, 42.1 Construction of roads and railways, and 43.3 Building completion and finishing. These materials are crucial for the construction and infrastructure development sectors, enabling the creation of a wide range of built environments.
