SUPPORT ELEMENT AND SUPPORT ELEMENT SYSTEM, ESPECIALLY FOR CONCRETE CONSTRUCTIONS AND CONCRETE BUILDING COMPONENTS

摘要

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 create a support element that comprises at least one supporting fiber system embedded in a binder and is characterized by excellent vapor permeability and at the same time by high stability and good modulus E values. Another corresponding aim applies to a support element system regarding the binder contained in the adhesive between the ground and the support element. The first aim is achieved by the fact that the binder contains at least one polymer component that is provided with a minimum shear modulus G of 3000 N/mm² and a minimum tensile strength of 10 N/mm² in the cured state, said binder containing at least one crystallite moiety which permeates the supporting fiber system at least in part while being provided with a maximum effective water vapor diffusion resistance factor µ of 18,000 in the cured state of the polymer component thereof. The other aim is achieved by the fact that the adhesive contains at least one polymer component that is provided with a minimum shear modulus G of 5000 N/mm² and a minimum tensile strength of 10 N/mm² in the cured state while said adhesive contains a crystallite moiety which forms a solid dispersoid having a maximum effective water vapor diffusion resistance factor µ of 18,000 in combination with the adhesive polymer component.
