Cooperative Leichtbeton Werbegemeinschaft GesmbH

Cooperative Leichtbeton Werbegemeinschaft GesmbH (commonly shortened to Cooperative Leichtbeton or CL) is an Austrian cross-company information and advisory platform dedicated to lightweight concrete (Leichtbeton) and mineral wall construction. Rather than being a manufacturer itself, the organisation positions itself as a "firmenübergeordnete Informationsplattform" — a competence centre that informs, advises, supports and documents on all matters relating to lightweight concrete. Its stated goal is to establish itself in the market as a competence centre for lightweight concretes and mineral wall assemblies, serving builders, planning offices and producers through a broad network spanning the whole of Austria. The organisation's core services are informing and advising, matching clients with the right producers, on-site support at construction sites, active research and development, and public relations for cement-bound building materials. It also operates its own heat-flow measuring device for determining the lambda value (thermal conductivity) of building materials, acquired in 2016 and stationed at a state-accredited testing institute so that accredited certificates can be issued. Cooperative Leichtbeton promotes lightweight concrete as a purely mineral, hydraulically bound building material that combines technical and ecological progress with architectural and functional requirements. Its messaging emphasises sustainability and durability: lightweight concrete is described as 100% recyclable, heat-insulating, sound-absorbing, diffusion-open, weight-saving, mould-free, resource-conserving, long-lasting, stable, permanent, non-combustible and rot-proof. The platform claims over 100 years of experience with the material. The organisation is supported by companies from across the entire Austrian building-materials industry. According to its partner page, this includes the whole Austrian cement industry (represented by the VÖZ), many raw-material and input-material producers, a large part of the precast industry, the masonry-block industry and many ready-mixed concrete companies. Named partners include Alpacem Zement Austria, Danucem Wien, Doka Österreich, Holcim (Österreich), Holcim Beton (Österreich), IHAR Handels, Ing. Hans Lang, Kirschner & Zechmeister, Leube Gruppe, Liapor Werk Fehring, MABA Fertigteilindustrie, MAPEI Austria, Miralis, Ramböck Betonwerk, Alfred Trepka, Betonwaren Aichinger and others. The partner page thanks the companies that have supported CL through advice and action for over 25 years. Research activity includes an FFG-funded research project on "Absorptionsbeton" (absorption concrete), which explores the conversion of kinetic energy to avoid excessively severe impact deformation, with potential applications in road construction (tunnel portals) and in mining and avalanche protection. Another innovation theme is the 100% purely mineral, cement-bound building envelope — building the outer shell from foundation to roof entirely in mineral materials without any plastics while still achieving good thermal performance. Cooperative Leichtbeton is an Austrian private company (GesmbH). It is not a listed company and does not appear to be a subsidiary of a larger group; its identity is that of a cooperative industry association and marketing community for lightweight concrete.

Cooperative Leichtbeton Werbegemeinschaft GesmbH is an Austrian industry platform for lightweight concrete. Its partner page states that companies from across the building-materials industry have supported the organisation through advice and action for over 25 years, indicating that the cooperative has been active since at least the 1990s. The organisation describes itself as a "firmenübergeordnete Informationsplattform" — a cross-company information platform — rather than a manufacturer, and its role is to inform, advise, support and document on all matters relating to lightweight concrete. Over time, CL has built a network that spans the entire Austrian building-materials sector. Its partners include the Austrian cement industry as represented by the VÖZ (Vereinigung der Österreichischen Zementindustrie), raw-material and input-material producers such as Doka, Liapor, Mapei, Miralis, AIRium and IHAR, a large part of the precast industry (Romberger, TIBA, MABA, Instabloc, Trepka), the masonry-block industry (Lang, Aichinger, Ramböck, Kirschner) and many ready-mixed concrete companies. This breadth is presented as a distinctive feature: CL is supported by companies from across the entire building-materials branch. In 2016 the organisation decided to acquire its own heat-flow measuring device for determining the lambda value (thermal conductivity, in W/mK). The stated reason was that most measuring devices are not designed to measure concrete, its test specimens and samples from a single workpiece. The device is stationed at a state-accredited testing institute, enabling the issuance of accredited certificates. Both lambda 10/tr and lambda 23/80 — described as eminently important for the thermal assessment of building materials — can be determined with it. CL has also engaged in research and development. It carried out an FFG-funded research project on "Absorptionsbeton" (absorption concrete), whose theme was the absorption (conversion) of kinetic energy to avoid excessively severe impact deformation, with potential applications in road construction (tunnel portals) and in mining and avalanche protection. Another innovation theme promoted by CL is the 100% purely mineral, cement-bound building envelope: building the outer shell from foundation to roof entirely in mineral materials, without any plastics, while still achieving good thermal performance — made possible because various lightweight concretes also have very good heat-insulating properties. The organisation's long-standing message is that lightweight concrete is a purely mineral, hydraulically bound building material that combines technical and ecological progress with architectural and functional requirements. It highlights that lightweight concrete is 100% recyclable — one of the few building materials that can be fully converted back into a raw material without side effects or compromises — and that it is heat-insulating, sound-absorbing, diffusion-open, weight-saving, mould-free, resource-conserving, long-lasting, stable, permanent, non-combustible and rot-proof. CL claims over 100 years of experience with the material and quotes Dr. Miedler, former head of the material testing institute of the City of Vienna (MA39), as saying that "lightweight concrete is, in the sum of its properties, the ideal wall-forming material." Today, Cooperative Leichtbeton continues to operate as a competence centre and advisory platform for builders, planning offices and producers, with services including information and advice, producer matching, on-site support, research and public relations. It publishes a price list (e.g. Preisliste 2024) for its services.
