  Abstract: With increasing interest in the use of additive manufacturing techniques in the 
  construction industry, static rheological properties of fresh concrete have necessarily come into 
  focus. In particular, the knowledge and control of static yield stress (SYS) and its development over 
  time are crucial for mastering formwork-free construction, e.g., by means of layered extrusion. 
  Furthermore, solid understanding of the influences of various concrete constituents on the initial
