Description:

The Green Deal and the Paris Agreement have forced the construction industry to maintain a “zero
carbon” and “digital transformation” criteria through their production methods. These developments made
the concrete industry paradoxical in achieving optimization among improved performance, cost, and
sustainability. For example, mortars that produce structural elements with three-dimensional (3D) printers
use three times more cement than conventional concrete to control hydration and improve rheology. This
increases the production of high cement volumes and makes the environmental impact even more
pronounced.
The main objective of this study is to develop building materials suitable for 3D printing using locally
available soil. For this purpose, the rheological properties of the soil materials designed to be produced in
3D printers will be controlled by using bacterial cells. Microorganisms will stabilize natural clays (kaolin
and bentonite) to obtain a natural material. In the planned research, the rheological properties of the
printable material will be examined by determining the interaction of clays and microorganisms and
physiochemical changes. In this context, clays' physical and chemical properties will first be determined.
First, the interaction of cells with clay-based materials will be examined using Zeta potential
measurement, Fourier Transform IR, and Scanning Electron Microscopy.
