Manufacture of lime and plaster

NACE v2.1 Code: C23.52

About manufacture of lime and plaster

NACE code 23.52 covers the manufacture of lime and plaster, which are essential materials in the construction industry and various other applications. Lime, produced by heating limestone, is a versatile substance used in the production of cement, as a building material, and for water treatment. Plaster, on the other hand, is a building material made from gypsum, which is also used for decorative purposes. This industry plays a crucial role in supporting the construction sector and other industries that rely on these fundamental materials.

Production process

The manufacture of lime and plaster involves several key steps. For lime production, limestone is extracted, crushed, and then heated in a kiln to a high temperature, causing the release of carbon dioxide and leaving behind calcium oxide, or quicklime. The quicklime is then slaked with water to produce hydrated lime, which can be further processed into various lime products. Plaster is typically produced by grinding gypsum, which is then heated and mixed with water to form a paste that can be molded or applied to surfaces.

Production inputs

The primary raw materials required for the manufacture of lime and plaster are limestone and gypsum, respectively. In addition to these natural resources, the industry also relies on energy sources, such as fuel for the kilns, as well as specialized equipment like crushers, grinders, and mixing machinery. Water is another essential input for the slaking and mixing processes involved in lime and plaster production.

Production outputs

The main outputs of this industry are various forms of lime and plaster products. Lime can be used in the production of 23.51 Cement, as well as in the chemical industry, agriculture, and water treatment. Plaster is primarily used in the construction industry for plastering walls, ceilings, and other surfaces. The outputs of this industry may also be consumed by other NACE codes, such as 41.20 Construction of residential and non-residential buildings and 43.31 Plastering.
