Ciments du Katanga (CMKT or Cimenkat) is a company in the Democratic Republic of the Congo that makes cement and related products.

It was established during the copper boom of the early 1920s to supply the new mining and refining companies, including worker housing and industrial construction.

The ores from the rich copper mines of the region had to be refined to reduce their bulk, and thus cut transport costs.

[5] A fibrocement factory was established in 1929 to manufacture materials such as granites, artificial stones, tiles, pipes and corrugated roofing sheets.

On 13 February 1962 Ciments du Katanga transferred its property and facilities at Lubudi, and all its industrial and commercial activities, to a new company incorporated under Congolese law, Ciments et materiaux de construction du Katanga (CIMENKAT).
