Evonik solutions for 3D concrete printing
- Rheology control
- Accelerated curing speed
- Mechanical strength
3D concrete printing is an efficient, flexible and resource-saving construction technology with great potential for the future. The process enables fast and site-independent production of construction elements or even complete buildings. The concrete mixture requires specific viscoelastic properties, which can be achieved by silica addition.
In 3D concrete printing, components are built up layer by layer. The challenge is to achieve a balance between dimensional stability, fast curing, and bonding. SIPERNAT® 380 precipitated silica improves both the rheological properties and the setting behavior of concrete mixtures. This specialty silica supports precise control of rheology, accelerates curing, promotes adhesion and improves the mechanical strength of 3D printed structures. By these effects SIPERNAT® 380 enables 3D concrete printing to become an economically attractive construction technology.
