Overview
Cimpor, short for Cimentos de Portugal, is a Portuguese-origin cement and construction-materials business established in 1976. It developed from a national cement producer into one of Portugal's most internationally oriented building-materials groups, combining manufacturing, distribution, and sales across multiple geographic markets. Its principal activities have included cement, hydraulic lime, ready-mixed concrete, aggregates, precast concrete, and dry mortars. The company's Portuguese industrial base has included major cement works at Souselas near Coimbra, Alhandra near Vila Franca de Xira, Loulé, and Cabo Mondego near Figueira da Foz. From Portugal, Cimpor expanded into a broad network of markets spanning Europe, North Africa, Latin America, sub-Saharan Africa, and Asia. The international footprint described in reference material includes Portugal, Spain, Morocco, Brazil, Tunisia, Turkey, Cape Verde, Mozambique, China, Egypt, and South Africa. The business has therefore been associated not only with domestic cement supply but also with infrastructure and construction-materials demand in emerging and developing markets. Cimpor was formerly a public company traded on Euronext Lisbon and included in the PSI-20 benchmark. Its ownership changed substantially during the consolidation of the international cement industry. In 2010, Brazilian groups Camargo Corrêa and Votorantim accumulated significant stakes while resisting a proposed takeover by Companhia Siderúrgica Nacional. In 2012, Camargo Corrêa, through InterCement, increased its position to a dominant shareholding after acquiring additional shares and exchanging assets with Votorantim. This made InterCement the controlling shareholder and left only a minority public float for a period. Shareholders voted in June 2017 to permit the acquisition of the remaining publicly held shares, supporting the removal of Cimpor from the Lisbon exchange. The subsequent history was marked by further portfolio restructuring rather than simple expansion. In January 2019, the OYAK Group acquired Cimpor's business units in Portugal and Cape Verde, with Taiwan Cement Corporation participating as a minority shareholder. Taiwan Cement later completed the acquisition of all Cimpor assets in Portugal and Cape Verde in early 2024. This transaction formed part of Taiwan Cement's international expansion and strengthened its presence in strategically important cement markets. Because ownership and operating assets have changed over time, the Cimpor name should be understood as a brand and business platform whose geographic scope has been reorganized through acquisitions and divestments. Historical descriptions of Cimpor's global network should not automatically be read as a statement of its current ownership of every country operation once associated with the group. Its enduring market identity is that of a large Portuguese cement producer and a supplier of complementary construction materials, including cementitious products, concrete, aggregates, precast products, and dry mortars.
History
Cimpor was founded in 1976 as Cimentos de Portugal and became one of Portugal's principal cement groups. Its development was tied to the growth of construction and infrastructure demand in Portugal, supported by a network of large cement plants. Important Portuguese facilities included Souselas near Coimbra, Alhandra near Vila Franca de Xira, Loulé, and Cabo Mondego near Figueira da Foz. The company later pursued international growth and developed operations or business interests across a wide group of markets. Reference material associates Cimpor with Portugal, Spain, Morocco, Brazil, Tunisia, Turkey, Cape Verde, Mozambique, China, Egypt, and South Africa. In addition to cement manufacturing and marketing, its activities extended to hydraulic lime, concrete, aggregates, precast concrete, and dry mortars. This broadened the business from a conventional cement producer into a more diversified construction-materials supplier. Cimpor was listed on Euronext Lisbon and was included in Portugal's PSI-20 index. Its ownership became the subject of a major corporate contest in 2010, when Companhia Siderúrgica Nacional proposed a takeover while Camargo Corrêa and Votorantim acquired sizeable holdings. The ownership structure subsequently consolidated around Camargo Corrêa. In 2012, through its subsidiary InterCement, Camargo Corrêa raised its stake to approximately 94.8 percent after further share purchases and an exchange of assets with Votorantim. The company consequently became effectively controlled by a single shareholder, although a public minority remained for several years. On 21 June 2017, Cimpor shareholders approved a proposal enabling Camargo Corrêa, then holding approximately 95 percent of the company, to acquire the remaining publicly held shares. The decision supported Cimpor's delisting from the Lisbon stock exchange and marked the end of its period as a widely traded public company. The following phase involved restructuring and the transfer of regional assets. In January 2019, OYAK acquired Cimpor's Portugal and Cape Verde business units, while Taiwan Cement Corporation participated as a minority shareholder. In early 2024, Taiwan Cement completed the acquisition of 100 percent of Cimpor's assets in Portugal and Cape Verde. The transaction was presented as part of Taiwan Cement's broader international growth strategy and increased its presence in important cement markets. Cimpor's historical corporate identity therefore spans three stages: the creation of a Portuguese national cement group, its transformation into an international construction-materials business, and the subsequent reorganization of its assets under larger global cement groups. The brand remains associated with cement, concrete, aggregates, and related products, but the ownership and geographic composition of the business have changed significantly over time.

Products and positioning
A Portuguese-origin cement and construction-materials supplier with a historically broad international footprint and strong exposure to infrastructure and construction markets.
Core construction material
Cement
Cement is Cimpor's central product category and the foundation of its historical manufacturing and marketing operations. The portfolio includes Portland and blended cement types used in general construction, infrastructure, commercial building, and other applications requiring hydraulic binding materials. Product availability and specifications vary by market and local standards.
Binders
Hydraulic lime
Hydraulic lime is a complementary binder product associated with Cimpor's construction-materials activities. It can be used in mortars and building applications where lime-based performance characteristics are required. The reference material identifies hydraulic lime as part of the group's product scope but does not provide a detailed product catalogue.
Concrete
Ready-mixed concrete
Cimpor has been involved in the production and marketing of concrete, including ready-mixed concrete supplied for building and civil-engineering projects. This activity extends the company downstream from cement manufacturing and allows it to serve contractors and project-based customers with formulated concrete products.
Construction materials
Aggregates
Aggregates form another part of Cimpor's broader construction-materials offering. They are used in concrete, road construction, foundations, and other civil-engineering applications. The group has historically marketed aggregates alongside cement and concrete, although specific current operating locations are subject to ownership and portfolio changes.
Concrete products
Precast concrete
Precast concrete is included among the product areas historically associated with Cimpor. It covers factory-produced concrete elements manufactured before delivery to a construction site. The available reference material does not identify individual product models, brands, or current production sites.
Mortars
Dry mortars
Dry mortars complement Cimpor's cement, lime, and concrete activities. These factory-formulated products are used in masonry, rendering, repair, and other construction applications. The reference material confirms the category but does not specify a complete current range or detailed technical subcategories.
