Methods including preparing a mixture including a binder composition containing at least one binder and at least one mineral filler, and curing the mixture to produce a material having improved electrical conductivity at 20° C., where at least 20% by weight of the at least one mineral filler is iron-containing slag.

Conductive mortar

A curable binder composition includes: a) at least one organic binder selected from the group made of a1) epoxy resins and curing agents for epoxy resins and a2) polyisocyanates and polyols, and b) at least 50% by weight of slag based on 100% by weight of the binder composition.

Slag-containing polymer concrete and grouting mortar

A composition including cement, filler, polymer and a compound having epoxide groups and also an amine, wherein the composition contains more than 10% by weight of cement and at room temperature is present as storage-stable free-flowing powder and/or granular material. When mixed with water, the composition makes polymer-modified mortars having good processability, excellent adhesion, strength, water impermeability, chemical resistance and quick coatability possible.

Single component epoxy resin cement mortar

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.
