To provide a blast furnace slag-type paint using a liquid inorganic material composed of a fluid suspension.

A blast furnace slag-type two-part paint in which a stabilized aqueous suspension containing the following blast furnace slags is contained as the main agent, an alkaline liquid having dissolved therein sodium silicate, sodium carbonate, or potassium carbonate that induces a hydraulic reaction of the suspension serves as the hydraulic reaction inducer, and the main agent and the hydraulic reaction inducer are separately packaged.

<Components of the main agent> (A) 0.5 to 42% by weight of a high-blast-furnace-slag-content blast furnace slag having a blast furnace slag content of 60% or more with respect to the total weight of the blast furnace slag; (B) 0.1 to 20% by weight of a blocking agent containing a phosphorus-containing compound; (C) 0.3 to 5%, preferably 0.3 to 2.5% of a blocking agent differing from a phosphorus-containing compound; (D) water retention agent; others.

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.

A non-polar reaction resin mixture can be used to improve the adhesion of a mortar composition based on radically polymerizable compounds, in particular based on urethane (meth)acrylates, on the surface of semi-cleaned and/or damp boreholes in mineral substrates. The use of a non-polar reaction resin mixture in the corresponding mortar composition reduced the sensitivity thereof to dampness and inadequate cleaning conditions, so that mortar compositions are obtained overall which are characterized by improved robustness against external influences.
