A hardener composition can be used for a reactive resin system containing a reactive resin based on radically curable, ethylenically unsaturated compounds. The hardener composition contains a hardener for the reactive resin and a filler mixture. The filler mixture is composed of a first filler having a first average particle size d.sub.50,1 and a second filler having a second average particle size d.sub.50,2. The first average particle size d.sub.50,1 of the first filler is greater than the second average particle size d.sub.50,2 of the second filler (d.sub.50,1>d.sub.50,2). The ratio d.sub.50,1 to d.sub.50,2 (d.sub.50,1:d.sub.50,2) is in the range of 8:1 to 100:1. The filler mixture is useful, and a reaction resin system can contain the hardener composition.
