3D printing technology of concrete structures

Subject of Bachelor thesis was the gathering of information about 3D printing using concrete for designing new possible technologies. List of problems connected with material and technological properties in accordance with 3D printing was developed. Based on these findings new modification of fastener was developed. This fastener works with reaction time of few minutes. Testing was conducted using calorimetric measurements. Findings confirmed the usability of fastener in a cement paste. These results led to design of technology able to use the fastener. This technology was designed for as fast printing as technologically and materially possible in controlled environment. Furthermore, two new technologies for printing of extremely lightweight constructions from UHPC using 3D printing. First uses extrusion technique with screw feeder. Second method is based on binder jetting technology
