Djamaâ El Djazaïr Mosque in Algeria is the third largest mosque in the world after the two holiest places in Islam, the Grand Mosque in Mecca and Al-Masjid Al-Nabawi in Medina,as well as the first largest mosque in Africa.

Проектирана e от немските архитекти Drees & Sommer и Jürgen Engel Architekten, както и инженерната консултантска компания Cancer+PINE Ingenieure GmbH. Тази впечатляваща сграда се отличаваща с геометрична архитектура и бляскав правоъгълен двор, минаре с височина 265 метра със стъклена конструкция. Toвa e It is the tallest minaret in Africa, displacing the 210-meter minaret of the Hassan II Mosque in Morocco.

The interior of the mosque is distinguished by Andalusian architecture, decorated with wood, marble, alabaster, decorated with six kilometers of Quranic calligraphy and exquisite turquoise prayer mats. The simple, subdued design of the mihrab features only two small columns on either side. Covered by a lighted dome with a diameter of 50 meters, the main prayer hall can accommodate about 37,000 worshippers.

The entire complex accommodates up to 120,000 worshipers with parking spaces sufficient for 7,000 cars.

Following the architecture of traditional Islamic places of worship, the facade of the mosque is almost entirely formed of natural stone, which covers a total area of 95,000 m2. The construction of the mosque began in 2012, and construction continued for 7 years until 2019.

In designing and executing a building of this magnitude, combining a huge prayer hall, museum, research centre, conference centre, fire station, library and a college that is connected to apartments, a multitude of functional aspects had to be taken into account in order for the building to be not only aesthetically beautiful, but fully compliant with stringent design, functionality and quality requirements.

The height of the building, the materials used, the hot and humid climate of Algeria, the salty air, as well as the strong winds pose challenges for the architects and constructors with the problems of the load-bearing capacity of the building and the appearance of thermal bridges.

Some of the most important points in the construction of such a large-scale project in this case are the avoidance of thermal bridges and the associated thermal effects. As well as the use of expansion joints between prefabricated stairs, floors, between platforms and walls.

To prevent the appearance of thermal bridges, the contractors of the mosque trusted Schöck, which as an international specialist for thermal insulation products, offering the most suitable solution for both situations. The solution implemented in the building is the static-bearing Isokorb® T for thermal separation, the ready-to-install single-shear dowel ESD for the prefabricated stairs, and the heavy-duty dowel SLD for the stair landings.


Compared to conventional labor-intensive methods, these are extremely cost-effective solutions that allow horizontal movements and vertical transmission of the load in the building.

All dowels are made of stainless steel, so there is no danger of corrosion and their load capacity is guaranteed at all times. The ESD type single-shear dowel is the ideal fastener for applications with medium to low loads and relatively thin load-bearing components.

This type of dowel has now been redesigned in the form of the Schöck Dorn type LD and the diameter load capacity has been increased more than twice. In addition, the new LD type has European technical assessment approval and bears the CE mark. The SLD type is a heavy-duty dowel with a very high load capacity even in thin structural components, which is mainly used to connect statically important areas such as ceiling connections.
