The present invention relates to a method and a use of a composition, in each case for reducing the emission of environmentally harmful climate gases methane and/or carbon dioxide from farm manures during its storage. In some examples, the method and use involves bringing a composition comprising calcium cyanamide into contact with the farm manure.

Process for the reduction of gas emission from farm manure

The invention relates to aqueous solutions containing cyanamide, particularly storage-stable aqueous solutions containing cyanamide which contain a stabilizer and a surfactant.

Storage-stable solutions containing cyanamide

The invention relates to fiber-containing concrete compositions containing hydraulically setting binders, fillers, one or more fibers, and possibly other additives or admixtures, characterized in that one or more vinylester-ethylene copolymers are contained as additional components.

Fiber-containing concrete compositions

The invention relates to pervious concrete compositions containing hydraulic binder, filler and polymer, characterized in that the polymer present is a vinyl acetate-ethylene-copolymer having a glass transition temperature Tg of &#x2266;20&#xb0; C.

Pervious concrete composition

The invention relates to methods for applying wet concrete mixtures containing cement, fillers, water, one or more polymers, and possibly further admixtures or additives according to the wet-mix shotcrete method, characterized in that the wet concrete mixtures, which contain at least one polymer based on one or more vinyl esters of unbranched or branched alkyl carboxylic acids having 1 to 15 C atoms and possibly one or more further ethylenically unsaturated monomers, are put into a concrete spraying machine and are applied to a subsurface by means of the wet-mix shotcrete method with a layer thickness of &#x2267;3 cm.

Methods for applying polymer-modified wet concrete mixtures

The invention relates to fiber-containing pasty construction materials, containing a) one or more fillers, b) optionally additives, characterized in that they contain c) fibers, d) one or more polymers based on one or more ethylenically unsaturated monomers, having a glass transition temperature Tg of &#x2267;&#x2212;15&#xb0; C., e) &#x2266;5% by weight hydraulically setting binders and f) water, wherein the information in % by weight relates to the dry weight of the fiber-containing pasty construction materials. The invention also relates to a process for producing a reinforcing composition free of woven reinforcing fabrics.

Fiber-containing pasty construction materials

The invention provides hydraulically setting sealing composition based on a) a hydraulically setting compound out of the group comprising high-alumina cement, ordinary portland cement, blast furnace slag, b) protective-colloide stabilized polymer of one or more ethylenically unsaturated monomers in form of an aqueous polymer dispersion or a water-redispersible polymer powder, and c) one or more fillers.

Hydraulically setting sealing composition

The invention relates to methods for producing fiber-reinforced building-material coatings in that building-material coating agents containing mineral binders, optionally fillers, and optionally additives, are sprayed by means of a spray nozzle to form a building-material coating agent stream and one or more fibers are introduced into the building-material coating agent stream, and the fiber-modified building-material coating agent stream thus obtained then strikes a substrate, characterized in that the building-material coating agents additionally contain one or more polymers based on ethylenically unsaturated monomers.
