摘要:
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 ≧3 cm.
摘要:
The invention relates to aqueous preparations of polymer-modified setting accelerators, said preparations being characterised in that at least one setting accelerator and at least one cationically stabilised polymer are contained therein.
摘要:
The invention relates to a method for producing solid materials having an air content of ≦16 vol. % in relation to the total volume of solid materials, characterised in that hydraulically setting coating agents containing at least one cationic protective colloid are applied to an undersurface by means of mechanical methods using compressed air with air quantity factors of up to 100 or by manual methods.
摘要:
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.

摘要:
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.
