Summary of A 03
The gradation of material properties in concrete extrusion represents a particular challenge. Therefore, an innovative near-nozzle mixing system is being developed in A03 which enables immediate gradation of the fibre content and the density ranging from normal to lightweight concrete. Furthermore, in combination with insertion of vertical reinforcement over several layers a 3D transmission of tensile and flexural forces in the structure can be achieved. Thus, material properties, such as thermal conductivity and strength, can be precisely adjusted in the component.
