Support for concrete building components comprises assembly of support fibers embedded in uniformly distributed polymer binder of low diffusion resistance for water vapor when cured

摘要

Support for concrete building components comprises an assembly (TA) of support fibers which are embedded in a uniformly distributed polymer binder (B). This has a diffusion resistance for water vapor when cured of at most 50000, a shear modulus (G) of at least 3000 N/mm2 and a tensile strength of at least 10 N/mm2 Independent claims are included for: (a) a method for making the support by impregnating fibers under pressure with a polymer binder as described above; and (b) apparatus for carrying out the method comprising a binder injection system (BI) with an injection pressure chamber (DR1) which is in contact with the fiber assembly.
