Development of technologies for 3D printing of concrete structures
 Roupec, Josef ; Hela,, Vlastimil (referee) ; Hela, Rudolf (advisor)
Subject of dissertation was to itemize testing methods in fresh and hardened state of cement paste or concrete. During this process some new testing methods and specimen creation protocols were proposed. Further was created list of used materials and mix design processes which led to list of used 3D printing mixture designs and 3D printers. Next part of dissertation was devoted to creation of 3D printing mix design and observations based on them. At~the end is proposed a radical change in testing methods which utilizes latest advancements in computer science and could be part of digital design process for construction.

3D printing technology of concrete structures
 Roupec, Josef ; Bodnárová, Lenka (referee) ; Hela, Rudolf (advisor)
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.
