Abstract:
In a method for the 3D-printing of hydrous mineral binder compositions, an aqueous accelerator is mixed with the binder composition in a continuous mixer. The method is very robust and makes it possible to quickly print even large moulded bodies having a uniform aesthetic surface and very good strength development properties.
