Disclosed is an aqueous bonding composition comprising: (A) a modified saccharide which is a product of (a) a saccharide and (b) a radical initiator. The composition further preferably comprises a structure based on (c) an amine. The composition further preferably comprises (B) an inorganic acid salt. The formaldehyde-free aqueous bonding composition can contribute to an improvement in mechanical properties such as strength and elastic modulus of a molded article, compared to a formaldehyde-containing phenol resin composition.

The disclosure relate generally to structures, forms, and monoliths, and methods of preparing the same. This disclosure can produce uniform structured passageways or channels of active material, including adsorbent or catalyst, by imprinting or molding features into a paste on a support that can be subsequently assembled into a gas or liquid treating structure, i.e. a monolith. The paste, which can include an active material, binder, and other potential additives, can be applied to the support or pushed through a support (as in a mesh) as a thin film. The paste can be imprinted, stamped, shaped or otherwise handled to give features of desired height, shape, width, and positioning. When stacked or rolled, the features of one layer contact a subsequent layer, which seal to form passageways. The resulting structure can have high cell-density (>1000 cells per square inch) and a large volume fraction of active material.

The present invention relates to an inorganic binder system comprising blast furnace slag, and at least one solid alkali metal silicate, wherein the inorganic binder system is obtainable by co-grinding a mixture comprising the blast furnace slag and the at least one solid alkali metal silicate.

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.

The present disclosure relates to a cementious composition (e.g. for mounting a strain gauge within a gas turbine engine) comprising: part A comprising an acidic solution of a metal salt; part B comprising silica and one or more metal oxides; and part C comprising colloidal silica and/or a silicate solution. Part A may comprise an acidic aluminium phosphate solution. Part B may comprise one or more or all of titanium oxide, chromium oxide, alumina and barium oxide

An epoxy resin adhesive including at least one epoxy resin in the resin component, at least one adduct AD including primary amino groups which is free-flowing at room temperature and is formed from (i) at least one polyepoxide and (ii) at least one amine of the formula (I) and optionally further amines, and additionally at least one accelerator B having at least one dimethylamino group in the hardener component, and a total of at least 50% by weight of at least one inorganic filler. The epoxy resin adhesive has low odor and good processibility, rapidly builds up strength at room temperature and under cold conditions and, after curing, has high strengths, especially particularly high compressive strengths, and high bonding forces to substrates such as steel, carbon fiber composites (CRP) and concrete.

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 present invention provides a foaming agent composition for civil engineering-construction materials containing an anionic surfactant (A), a surfactant aid (B) and a water-insoluble or slightly water-soluble nonionic surfactant (C).

Disclosed is a construction material composition including a matrix predominantly containing an aluminum silicate compound, such as a metakaolin, and an alkaline activation solution. The composition is contains less than 10 wt. % cement or clinker and in that the metakaolin is a metakaolin obtained via flash calcination. The reaction between the components is carried out at a temperature less than 30 C. The method for manufacturing the construction material includes mixing the composition with various elements such as granulates, plant fibers, unfired clay, and expanding agents. It is particularly of use in producing floor, wall, or roof coating elements, prefabricated construction elements, or insulation, adhesive, or inorganic sealant modules.

Open time and creep resistance of hydraulically settable inorganic construction materials such as mortars and tile adhesives are both improved at the same time by the addition of a polymer mixture in the form of an aqueous dispersion or water-redispersible powder, containing one or more protective colloid-stabilized polymers having units derived from 20% to 30% by weight of vinyl chloride, 50% to 75% by weight of vinyl acetate, 5% to 20% by weight of ethylene, and one or more protective colloid-stabilized, vinyl halide-free polymers of one or more ethylenically unsaturated monomers.
