Cements and Hydraulic Lime

With a national production capacity of about 4 million tons of cement per year, Secil, through the Outão, Maceira-Liz and Cibra-Pataias plants, meets more than 35% of the cement needs in Portugal. The last two plants are part of the CMP, a company 100% owned by Secil.

Secil Outão

The Secil-Outão plant was established in 1904, in Setúbal, and is one of the largest cement plants in Portugal, with annual production capacity of around 2 million tonnes.

The characteristics of the valley in which the plant is located – with the raw materials required for production and easy road, rail and sea access (including its own wharf) – are all factors contributing to the success of one of largest companies in the Portuguese cement industry.

The Secil-Outão plant invests regularly in the modernization of the equipment that contributes to reducing the inevitable environmental impacts of the manufacturing process.


The Maceira-Liz plant was opened in 1923 and was the first in Portugal to produce Portland cement. With annual production capacity of about 1.5 million tons of cement, this unit has has also had a paper bags factory on its premises for over 50 years.

The Maceira-Liz plant is well documented in a museum, exhibiting its history since its inception. Like the other plants its focus is on technological modernization in order to minimize the environmental impacts of its operations.


The Cibra plant opened in 1950 in Pataias (Alcobaça), with the aim of exploiting the natural advantages of the region, whose stone and sand had the quality required for the production of white cement and which had already led to the manufacture in the area of the only binder used in the construction of the Alcobaça Abbey.

Both Cibra white cement and grey cement are produced in this plant, which has an annual production capacity of 620 million tonnes. Of these, 120,000 tonnes are of white cement, a product that is seen as strategic for the Group, the only producer of white cement in Portugal.

Commercial Warehouses

The numerous warehouses that Secil owns throughout in Portugal and the wide range of options for the supply, transportation and control in the loading operations of the material (bulk or bagged on pallets or in bulk package) mean that the company can remain close to its customers.

This is also the reason for Secil’s prioritization of sea transport. Hence the importance of the Secil-Outão private wharf which is use for the supply of the various maritime warehouses in Portugal and it is also a key element in cement and clinker exports to more than 30 countries. This structure has a very significant impact on the region as Secil is the largest loader by volume operating out of the Setúbal port.

Cimentos Madeira

Cimentos Madeira was incorporated in 1984, with Secil acquiring a minor holding, with operations in the reception, silo storage, bagging and marketing of cement, aggregates and ready-mixed concrete in the Autonomous Region of Madeira. In 2007, Secil acquired a majority stake in the company (57%), with the remaining capital owned by the Regional Government of Madeira.

Cimentos Madeira has also adopted a policy of expansion into other business areas in the cement branch, by acquiring Brimade, an aggregates company, and incorporating Beto Madeira, which operates in the production and sale of ready-mixed concrete.


Ready-mixed concrete is the second most important business area in the turnover of the Secil Group. The company is represented by Unibetão with 30 ready-mixed concrete plants covering almost the whole of the country.


Secil Britas, a company operating 12 quarries in Portugal, is one of the companies in the aggregates sector with capacity for granite and limestone extraction for construction. Brimade (Cimentos Madeira property) is another company in the aggregates area.


Secil operates in the industrial mortars market through Secil Argamassas, a pioneer in the production of Natural Hydraulic Lime and Dry Industrial Mortars in Portugal. The company was founded in 1891 and has five plants in the country, in Madeira, Pataias, Rio Maior, Montijo and Loulé.

The Secil Argamassas plants are equipped with the latest mortar manufacturing technology and have a vast range of products to guarantee the durability of the materials, the technical excellence of the solutions, advanced performance in application and the improved energy efficiency of buildings. Secil Argamassas currently exports its products to Spain, France, Denmark, United Kingdom, Ireland and Angola.

Environment and Energy

Through its commitment to the highest Sustainability standards in its production process, namely by including secondary raw materials, using alternative fuels and reducing CO2 emissions, the Secil Group is present in the energy market through Reficomb (recovery of non-metal waste), AVE (waste management) and Allmicroalgae (producer of microalgae biomass).
