Abstract
Fibers with crystallization seeds attached to its surface, method of making such composite fibers by surface treatment of fibers followed by either treating such fibers with premade crystallization seeds or by precipitation and direct crystallization of seeds onto pretreated fibers. Controlling and tuning the properties of inorganic binder compositions with fiber-bound crystallization seeds and thereby generating inorganic binder compositions with tailor-made characteristics.
Claims23
A plurality of individual fiber bodies having attached to the surface of such individual fiber bodies crystallization seeds wherein the crystallization seeds are attached to the individual fiber bodies via linker moieties, wherein the crystallization seeds are attached to the individual fiber bodies via covalently bound linker moieties in the presence of comb polymer, wherein the linker moieties are selected from one or more functional groups containing an amine, amide, phosphate or phosphonate functionality, and wherein the crystallization seeds are selected from calcium silicate hydrate, ettringite, or calcium sulfate dihydrate.
