Cement-free or cement-reduced low dust hybrid flooring compositions

Abstract

The invention relates to a multi-component composition comprising a solid component comprising calcined paper sludge and one or more aggregates, and a binder component comprising an organic binder selected from one or more polyols, one or more epoxy resins and a polymer latex dispersion, and, if the organic binder is one or more polyols or one or more epoxy resins, a hardener component comprising an isocyanate hardener for polyol or an amine hardener for epoxy resin, wherein the multi-component composition further comprises water which is contained in the binder component or, if present, in the hardener component. The composition is a cement-free or cement-reduced low dust hybrid composition and is suitable as a grout or for preparing floorings or coatings. The properties obtained are comparable to corresponding polymer cement concrete systems.
