Abstract: A method for the application of hydrous mineral binder compositions which contain fibres. An aqueous accelerator is mixed with the aqueous binder composition in a mixer shortly before the application. The method is very robust and makes it possible to quickly produce even large moulded bodies having a uniform surface and very good strength development properties.
