A mortar composition, in particular a leveling mortar composition, including: a) 3-45 wt. % of a hydraulic binder, b) 15-80 wt. % of lightweight aggregates, c) 5-50 wt. % of a polymer.

Leveling and noise reducing mortar composition

The use of an additive, including at least one water-soluble polymer, which is a homo-or copolymer of at least one monoethylenically unsaturated carboxylic acid, and optionally at least one alkali silicate as a liquefier for geopolymers. The additive can be produced in a simple and inexpensive manner and is particularly suitable for liquefying geopolymers, in particular geopolymers containing metakaolin.

Plasticizer for geopolymers

A multi-component composition is described that includes: A) a binder component (A) including at least one epoxy resin, B) a hardener component (B) including at least one amine compound as an amine hardener, and C) a solid component (C) including a hydraulic inorganic binder, wherein the hydraulic inorganic binder is a ternary binder composed of aluminous cement, calcium sulfate, and optionally Portland cement, wherein the solid component (C) includes 2 to 30 wt % aluminous cement, 1 to 16 wt % calcium sulfate, and 0 to 20 wt % Portland cement. The multi-component composition is suitable in particular as a self-leveling floor-leveling compound for a floor covering or as a mortar.
