The invention relates to reinforced concrete more particularly, prestressed concrete including at least one reinforcing element formed by a matrix based on a thermosetting synthetic material in which preferably more than 150000 practically parallel continuous filaments are obtained. The filaments 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 element has an improved resistance to alkali.
