Abstract

A curable binder composition includes: a) at least one organic binder selected from the group made of a1) epoxy resins and curing agents for epoxy resins and a2) polyisocyanates and polyols, and b) at least 50% by weight of slag based on 100% by weight of the binder composition.

First claim

The invention claimed is:

1. A method comprising
a step of grouting of machines or turbines with a curable binder composition comprising: a) at least one organic binder selected from the group consisting of a1) epoxy resins and curing agents for epoxy resins and a2) polyisocyanates and polyols, and b) at least 50% by weight of slag based on 100% by weight of the binder composition,
wherein the slag has a bulk density of at least 2.9 kg/l, and
wherein the slag is an iron-containing slag containing at least 8% by weight, of iron, calculated as FeO.

2. The method as claimed in claim 1 , wherein the binder composition contains 50% to 80% by weight, of slag, based on 100% by weight of the binder composition.

3. The method as claimed in claim 1 , wherein the slag is selected from the group consisting of blast furnace slags, steel slags, metallurgical slags, and slags from waste incineration.

4. The method as claimed in claim 1 , the slag has a particle size of 0.05 to 16 mm.

5. The method as claimed in claim 1 , wherein the slag particles are irregularly shaped and/or have a rough surface.

6. The method as claimed in claim 1 , wherein at least one further mineral filler selected from the group consisting of limestone powder, chalk, quartz powder, silica dust, titanium dioxide, baryte powder, and alumina is additionally present in the curable binder composition.

7. The method as claimed in claim 1 , wherein at least one wetting agent and/or dispersant, is present in the curable binder composition.

8. The method as claimed in claim 7 , wherein the slag and optionally also the at least one further filler, if present, are coated with the wetting agent and/or dispersant.

9. The method as claimed in claim 1 , wherein the curable binder composition is a multicomponent system comprising at least one resin component comprising at least one epoxy resin, and at least one curing agent component comprising at least one curing agent for epoxy resins, wherein slag and optionally further ingredients are present in the resin components, in the curing agent components and/or in any further components optionally present.

10. The method as claimed in claim 1 , wherein the curable binder composition is a multicomponent system comprising at least one polyisocyanate component comprising at least one polyisocyanate, and at least one polyol component comprising at least one polyol, wherein slag and optionally further ingredients are present in the polyisocyanate components, in the polyol components and/or in any further components optionally present.
