Additive manufacturing of concrete wall structures

3D concrete printing is a perspective technology for sustainable construction and realization of sophisticated architectural projects. The current research proposes the thermal engineering calculation wall structure based on printed element total thickness 150 mm with internal air layer about 75 mm. mixture was designed addition perlite as filler in dosage 8 % by weight cement. process performed printer Contour Crafting type through nozzle size 20 implemented A++ energy consumption class. perlit has resistance comparable one structures brick aerated concrete. decreased 100 50 comparison concrete, respectively. In to calculations, visual assessment surface quality elements performed.
