An additive, in particular a shrinkage reducing agent, for mineral binder compositions including at least one super absorbent polymer SAP and at least one defoamer D. Further, a mineral binder composition including the additive, processes and methods for the mixing thereof, and to hardened articles obtainable therefrom.

Shrinkage reducer for mineral binder composition and its use

An improved mineral binder composition including: a mineral binder including at least 30 weight-% slag, based on the weight of the mineral binder, an activator for the hydration of the slag consisting of or comprising calcium hydroxide and a co-activator consisting of or including at least one salt selected from the group consisting of lithium carbonate, lithium sulfate and sodium carbonate.

Activation of ground granulated blast furnace slag

A dry mineral binder composition includes cement and mineral fillers for the manufacture of molded parts by way of 3D printing. The binder composition additionally contains at least one aluminum sulfate-based accelerator, at least one polycarboxylate ether-based super-plasticizer and at least one rheology additive.

Mineral binder composition for 3D printing

An accelerator powder for cement and also rapid-setting binder compositions which contain the accelerator powder and the use in mortar or concrete. The accelerator powder includes from 10 to 99.7% by weight of a water-insoluble mineral powder P and from 0.3 to 90% by weight of at least one compound V selected from the group consisting of alkali metal halides and alkaline earth metal halides, alkali metal nitrates and alkaline earth metal nitrates, alkali metal nitrites and alkaline earth metal nitrites, alkali metal thiocyanates and alkaline earth metal thiocyanates and hydroxyalkylamines or salts thereof, and mixtures thereof.
