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.

A method of cementing may include: mixing at least a cement dry blend, water, and a liquid activated pozzolan additive to form a cement slurry, wherein the liquid activate pozzolan additive comprises a carrier fluid and an activated pozzolan; introducing the cement slurry into a wellbore penetrating a subterranean formation; and allowing the cement slurry to set.

The present invention relates to a construction chemical composition comprising Portland cement, a water retention agent, a dispersing agent, and a hardening accelerator comprising calcium-silicate-hydrate, as well as a mortar composition containing said construction chemical composition. Although the composition is based on Portland cement it has a pull-off strength after 6 h meeting the DIN requirements and can therefore be used as a fast setting tile mortar.

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.
