Prvok - Issue on 3D printing concrete building

Prvok is the first 3D printed concrete floating house in Czech republic. Additive manufacturing - printing became a synonym of sustainable building 21st century. Its experimental manner and lack world's standardisation ISO approvals hold method on edge usability applicability stop broader spread application practice. Furthermore, used material was newly developed cement composite prefabricated mixture mady by Master Builder Solutions with polypropylene plastic micro-fibres, which not previously tested large structures. What we achieved, practical realisation fully equipped functioning as habitable statue for public event. In order to fulfil request insulation avoiding heat bridges together investing least possible, parametrically designed implemented wall system construction. be able open structure public, it universal loading machines at Faculty civil engineering CTU Prague scale 1:1. Testing fragments walls were also part research goals, led us final design. this paper, present results experiment experimentally obtained data.
