Around six kilometres from the historic heart of the Algerian capital Algiers, a temple of magnificence soars into the sky. On a site measuring a good 26 hectares directly on the Bay of Algiers, the Jemma el Djazair, the third-largest mosque in the world, is under construction. Only the two pilgrimage sites in Mecca and Medina are larger. The load-bearing elements of the imposing structure are 618 spun concrete columns, produced in the concrete pole factory at FUCHS Europoles headquarters in Neumarkt. The spun concrete columns up to 36 m high are a distinguishing feature of a 'building for eternity' that is in a class of its own.
A multifunctional complex
At a height of 265 m, the minaret of the Great Mosque of Algiers will be the tallest in the world. It rises above the gigantic complex that extends over an area of 375,000 m2 with just under 1.8 million m3 enclosed space. The principal ANARGEMA (Agence Nationale de Réalisation de Gestion de la Mosquée d’Algérie) is investing over €1 billion to build it. There is room for 120,000 people in the complex, which apart from the house of worship itself also incorporates a large number of cultural and religious establishments. For example there will be a museum and a library with over a million works, as well as apartments and a kindergarten.
Special measures for a special project
Despite its enormous size, the overall concept by architects KSP Jürgen Engel is airy and delicate. This impression is evoked above all by the white colour and the slender columns in spun concrete, which are the responsibility of the specialists from FUCHS Europoles.
The production and delivery for the largest single order in the history of FUCHS Europoles calls for special measures,” says Michael Biederer, the Technical Project Manager at FUCHS Europoles. “For the mosque columns we set up a separate storage yard directly next to the plant and we fitted the production facility with new cranes and a new concrete mixing facility.
