A method for making geopolymer cementitious binder compositions for cementitious products such as concrete, precast construction elements and panels, mortar and repair materials, and the like is disclosed. The geopolymer cementitious compositions of some embodiments are made by mixing a synergistic mixture of thermally activated aluminosilicate mineral, calcium aluminate cement, a calcium sulfate and a chemical activator with water.

The invention relates to screed mixtures, comprising an inorganic binder, processing additives and drying additives. Self-levelling floor screeds according to the invention can be produced from these screed mixtures, said self-levelling floor screeds drying much more quickly than self-levelling floor screeds with the same composition, but which contain no drying additives.

Cementitious binder compositions for cementitious products including a hydraulic cement-based reactive powder blend, an inorganic flow control agent, and a metal-based dimensional movement stabilizing agent including at least one member of the group of lithium salt and lithium base, and methods for making the cementitious binder compositions.

The invention relates to a low-carbon-footprint hydraulic binder for mortar, and to mortar containing such a hydraulic binder. The hydraulic binder for mortar comprises at least 60% steel slag and at least one catalyst.

Stucco-cement compositions with a shortened drying time, lighter weight, high strength and reduced expansion, the compositions comprising expanded perlite and preferably also calcium aluminate cement and/or calcium sulfoaluminate cement, and methods for making and using these compositions, including pourable and/or pumpable floor underlayment slurries and methods for forming high strength underlayment on different substrates.

A kit of parts suitable to form a waterproofing membrane consisting of a first component A including or consisting of a) 5-60 mass parts, preferably 30-60 mass parts, more preferably 45-55 mass parts, of a hydraulic binder, b) 0.5-15 mass parts, preferably 1-5 mass parts of at least one synthetic polymer, c) 20-80 mass parts, preferably 30-50 mass parts of aggregates, and d) optionally further additives and a second component B including or consisting of an aqueous emulsion of bitumen.

The invention relates to a composition comprising () at least one water-soluble polymer based on (a) 5 to 40 wt % of at least one monomer of the formula (I) and (b) 5 to 95 wt % of at least one monomer (b) which comprises acid groups and is different from monomer (a), and () at least one associative thickener. Further disclosed is a mixture comprising an inorganic binder and also the composition of the invention. A further aspect of the present invention is the use of the composition of the invention as a rheological additive.

The present invention concerns an additive for construction chemical compositions, in particular mortar and cement compositions. The additive comprises at least one amide or ester of a sugar acid and at least one water-soluble comb polymer which contains, on the main chain, acid functions and side chains having ether functions. The additive is useful for retarding the hardening of a construction chemical composition.

A method for making geopolymer cementitious binder compositions for cementitious products such as concrete, precast construction elements and panels, mortar, patching materials for road repairs and other repair materials, and the like is disclosed. The geopolymer cementitious compositions of some embodiments are made by mixing a synergistic mixture of thermally activated aluminosilicate mineral, calcium sulfoaluminate cement, a calcium sulfate and a chemical activator with water.

Thermally conductive cementitious compositions for use in flooring installations that are applied over a heat radiating flooring system to increase the thermal conductance of the flooring system and increase the rate of heating the flooring system. The thermally conductive cementitious compositions include a cementitious composition, amorphous flake graphite carbon, and an aqueous solution suitable for use as a thermally conductive mortar, grout or adhesive for flooring installations. The thermally conductive cementitious compositions also include a cementitious composition, mesh fine aluminum oxide, mesh coarse aluminum oxide, and an aqueous solution that provides a thermally conductive mortar, grout or adhesive for use in flooring installations.
