Support element and support element system, especially for concrete constructions and concrete building components

Abstract

The invention relates to a support element, especially for concrete constructions and concrete building components, comprising at least one supporting fiber system embedded in a binder. The aim of the invention is to provide a support element that comprises at least one supporting fiber system embedded in a binder and that is characterized by excellent vapor permeability and at the same time by high stability and good modulus E values. To this end, the binder contains at least one polymer component that has a specific water vapor diffusion resistance value μ of at least 20000, a modulus E of transverse elasticity G of at least 3000 N/mm2 and a tensile strength of at least 10 N/mm2. The binder further contains at least one granular component that extends at least through parts of the supporting fiber system and that forms together with the supporting fiber system, in the cured state of the binder/polymer component, a solid body dispersoid with a water vapor diffusion resistance value μ of not more than 10000.
