Enhancer element synthetic material for use in reinforced concrete, more particularly prestressed concrete, reinforced concrete provided with such reinforcement elements and process for making reinforcing elements, and reinforced and prestressed concrete.

摘要

The invention relates to a reinforcing strip (1) applicable in reinforced concrete, more particularly prestressed concrete, formed by a matrix based on a thermosetting synthetic material in which preferably more than 15000 practically parallel continuous filaments (5) are obtained.… The filaments (5) are formed from an organic polymer selected from the group of aromatic polyamides, such as polyparaphenylene terephthalamide, or from polyethylene, polyvinyl alcohol or polyacrylonitrile via solvent spinning.… The matrix is formed from a synthetic material based on epoxy resin and/or bismaleimide resin.… The reinforcing strip (1) has an improved resistance to alkali.… The invention also relates to reinforced concrete comprising said strips (1).
