Perspectives of application of aerated concrete for 3D building printing

Abstract

Adaptation of the technology for a 3D building printing system aimed at producing non-autoclaved aerated concrete allows solving a task of how to create wall structures with high thermal insulation properties without using other materials, and with the increase of molding devices’ productivity due to extension in layered mass. The main step towards the adaptation is the separation of the molding aerated concrete mixture into two components: basic and activating aerated processes, setting up and hardening. Mixing the components should take place in the continuous mode directly before extrusion.
