In view of the climate targets, the construction industry is being challenged to rethink its practices in order to drastically reduce CO₂ emissions as well as resource and energy consumption. A promising approach is to replace conventional concrete with cement-free alternatives. That is where KIBECO Cleancrete Oulesse comes in as a pioneering, cement-free solution for your construction project.
KIBECO Cleancrete Oulesse. Cement-free concrete.
The cement-free concrete substitute
KIBECO Cleancrete Oulesse is a cement-free alternative for various applications in construction. The binder used, which was developed in collaboration with ETH spin-off Oxara, mainly comprises ground demolition materials, thus strengthening the material cycle. For example, cement-free concrete with strengths of up to 25 MPa and high water resistance is not only possible but also ideal for a wide range of applications.
Benefits of KIBECO Cleancrete Oulesse
- 0% cement
- Circular, up to 60% CO₂ reduction
- No energy-intensive firing process
- Reuse of demolition materials
- Wide range of applications up to 25 MPa

Application areas
Load-bearing walls
Partition walls and walls with load-bearing properties are both highly compatible with KIBECO Cleancrete Oulesse concrete.
Floor
KIBECO Cleancrete Oulesse Concrete can be used for floors with or without static requirements, including underfloor heating.
Lean concrete
KIBECO Leancrete Oulesse offers a cement-free alternative to conventional lean concrete for simple applications, such as blinding layers or base layers.
Enveloping concrete
As enveloping concrete, KIBECO Cleancrete Oulesse is ideally suited for sheathing cables or installation components.
Filling concrete
KIBECO Cleancrete Oulesse can be used as a pumpable, easily compacted filling concrete for filling cavities or excavation pits.
FAQ about KIBECO Cleancrete Oulesse
Here you will find answers to the most frequently asked questions about application, benefits and sustainability.
-
KIBECO Cleancrete Oulesse is an innovative, cement-free concrete specifically developed to reduce the environmental impact of construction. It offers a sustainable alternative to conventional concrete for a broad range of applications up to 25 MPa.
-
Unlike conventional concrete, KIBECO Cleancrete Oulesse does not contain cement, resulting in a significant reduction of CO₂ emissions. Despite the cement-free composition, the strength development is comparable to conventional cement-bonded concrete.
-
KIBECO Cleancrete Oulesse contributes to reducing the carbon footprint as it is produced without cement. This significantly mitigates the environmental impact compared to conventional concrete. In addition, the binder consists predominantly of ground demolition materials, which strengthens circular use.
-
KIBECO Cleancrete Oulesse is suitable for lean and permeable concrete applications as well as structural concrete for indoor applications. The cement-free product can also be used as enveloping and filling concrete.
-
The binder Oxacrete Oulesse consists of two components. The first is finely mixed rubble, which serves both as a filler and as an activatable mass. The second is the activator, which consists of mineral salts.
-
Like conventional structural concrete, KIBECO Cleancrete Oulesse is produced in the concrete plant and delivered to the construction site by mixer truck. It is placed in the formwork and post-treated as usual. No additional training is required for construction company staff.
-
Oxara is an innovative start-up specialising in the development of sustainable building materials. In collaboration with KIBECO, Oxara has developed cement-free concretes such as KIBECO Cleancrete Oulesse and Nossim, which offer an environmentally friendly alternative to conventional concrete solutions and help reduce CO₂ emissions.
