Manufacture of cement, lime and plaster

NACE v2.0 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 residential, commercial, and public works projects. The production of these materials is a capital-intensive process, requiring significant investment in specialized equipment and facilities to meet the high demand from the construction sector and other downstream industries.

Production process

The manufacture of cement, lime, and plaster involves several key steps. Cement production typically begins with the extraction and crushing of raw materials such as limestone, clay, and gypsum. These materials are then ground, blended, and heated in a kiln to produce clinker, the primary ingredient of cement. The clinker is then ground with other additives to create the final cement product. Lime is produced by heating limestone or dolomite in a lime kiln, while plaster is made by heating and grinding gypsum.

Production inputs

The main inputs for the manufacture of cement, lime, and plaster include raw materials such as limestone, clay, gypsum, and dolomite. Additionally, this industry requires significant energy inputs, primarily in the form of fuel for the high-temperature kilns used in production. Specialized machinery, including crushers, grinders, and kilns, are also essential for the manufacturing process.

Production outputs

The primary outputs of NACE code 23.5 are cement, lime, and plaster. These materials are then consumed by a range of other industries, most notably 41.2 Construction of residential and non-residential buildings and 42.1 Construction of roads and railways. Cement, in particular, is a crucial input for the construction of buildings, infrastructure, and various other concrete-based projects.
