KIBECO Cleancrete Nossim is a cement-free, stabilized cast clay that has been specially developed to reduce the environmental impact of construction. It offers a sustainable alternative to conventional concrete for non-load-bearing components and floors and a useful addition in hybrid buildings.

In contrast to conventional concrete, KIBECO Cleancrete Nossim contains no cement, which significantly reduces CO₂ emissions. Clay is a natural and local building material that is a waste product in the form of filter cake and is reused in cast clay instead of being landfilled. It is also open to diffusion, which means that it can absorb, store and slowly release moisture. Thanks to its high heat storage capacity, it contributes to the energy efficiency of buildings and ensures a pleasant indoor climate in both summer and winter. This feature makes it an excellent storage medium and an ideal complement to wood, which does not have this ability. In addition, cast clay offers good sound insulation properties and fire protection. It enables a wide range of aesthetic design options that emphasize the natural charm of the material.

KIBECO Cleancrete Nossim helps to reduce the CO2 footprint as it is produced without cement. This significantly reduces the environmental impact compared to conventional concrete.

KIBECO Cleancrete Nossim is based on environmentally friendly materials. It can be used for a variety of building components, including non-load-bearing interior walls, screeds, terrazzo floors, furniture and hybrid components in combination with wood. It should be protected from environmental influences such as rain and frost.

In hybrid construction, different materials are combined to make the most of the strengths of each one. Cast clay fits perfectly into this concept as it is sustainable and circular, which contributes to the principles of hybrid construction. Cast clay can be integrated into both traditional and modern construction methods. It complements steel or wood, for example, by improving heat storage and moisture regulation.

Cast clay is ideal for applications in a home. A stable base, such as cork insulation or a load distribution board, is required. The installation thickness should be at least 8 cm. Cast clay is also compatible with underfloor heating systems. One particularly attractive option is to turn it into a terrazzo floor, which is robust and easy to maintain and creates a pleasant indoor climate.

The Oxacrete Nossim binder is a specially developed mixture of mineral salts. It causes the clay to liquefy  in order to ensure installation in a similar way to conventional concrete. This is followed by strength development, which allows the formwork to be removed after four days. The final strength is achieved by air drying as with conventional clay building materials.

KIBECO Cleancrete Nossim is produced like conventional structural concrete in the concrete plant and delivered to the construction site with a truck mixer. The poured clay can also be pumped, which enables flexible use in different construction projects. No additional training is required for construction company workers.

Oxara is an innovative startup specializing in the development of sustainable building materials. In collaboration with KIBECO, Oxara has developed cement-free concretes such as KIBECO Cleancrete Nossim and Oulesse, which offer an environmentally friendly alternative to conventional concrete solutions and help to reduce CO2 emissions.
