Our Building Material Solutions
Cleancrete
Cleancrete is the building material containing our Oxacrete admixure. It is based on earthen excavation material and can include construction waste. Cleancrete can be applied to build floors, screed, non-load bearing walls and interior and exterior elements.
Impact
- cement-free
- high circularity
- earth-based
- up to 90% CO2 reduction compared to conventional cement based concrete
- low energy intensity
Cleanbrick
Oxabrick admixture is used to produce Cleanbricks with extrusion or compression processes. Cleanbricks are cement-free and non-fired, which reduces the environmental impacts of the material. Cleanbrick can be used to construct masonry walls.
Impact
- non-fired
- cement-free
- high circularity
- earth-based
- up to 85% CO2 reduction compared to conventional fired bricks
- low energy intensity
