Beschreibung
Zusammenfassung:	The present invention relates to a sizing composition for reinforcing glass fiber strands, which comprises a silane coupling agent, a polyurethane film-forming agent including a blocked isocyanate and water. The invention also relates to glass fiber strands onto which the sizing composition has been applied, and to concrete reinforced with said glass fiber strands. La présente invention porte sur une composition d'ensimage pour des brins de fibre de verre de renforcement, qui comprend un agent de couplage silane, un agent de formation de film de polyuréthane comprenant un isocyanate bloqué et de l'eau. L'invention porte également sur des brins de fibre de verre sur lesquels la composition d'ensimage a été appliquée et sur du béton renforcé par lesdits brins de fibre de verre.
