The invention pertains to the fields of chemistry and construction and relates to surface-modified glass fiber for reinforcing concrete, such as those which can be used in textile-reinforced concrete (textile concrete), for example. The object of the present invention is to provide surface-modified glass fibers for reinforcing concrete, which glass fibers are at least substantially protected against an alkaline attack caused by the calcium hydroxides released during the cement reaction and/or dissolution and leaching processes generated thereby. The object is attained with surface-modified glass fibers for reinforcing concrete which are at least partially covered at least with a hydrolysis-stable and alkali-resistant cationic polyelectrolyte and/or hydrolysis-stable and alkali-resistant cationic polyelectrolyte mixture and/or with a hydrolysis-stable and alkali-resistant polyelectrolyte complex and coupled to the glass fiber surface via a (polyelectrolyte) complex formation process by means of ionic bonding, with the hydrolysis-stable and alkali-resistant polyelectrolyte complex A thereby being formed, wherein at least one additional (co)polymer at least partially covers the polyelectrolyte complex A and is coupled with the polyelectrolyte A via ionic and/or covalent bonds.
