A 2-component composition is disclosed which contains an inorganic binder as well as a curing agent composed of water or an aqueous solution. The composition also contains substances which regulate solidification and curing, as well as, if necessary, conventional amounts of slag powders, fillers and blowing agents. The composition is distinguished by the fact that it cures rapidly even at low temperatures and can be used in small amounts. As a result, the composition is particularly suitable as a dowelling composition for fastening anchor rods in boreholes.

Compositions which set in the presence of water and their use

A two-chamber cartridge for fastening anchor elements in holes of a support structure is prepared. The chambers contain cycloaliphatic compounds and the reaction initiators. The separator separating the two chambers is destroyed inside the bore hole so that the mixing of the cycloaliphatic compounds and the reaction initiators can take place.

Cartridge having hardenable cycloaliphatic derivatives for bore

A composition and method are disclosed whereby the formation of geopolymers from curable, inorganic, stone-forming SiO.sub.2 and Al.sub.2 O.sub.3 containing compositions is accelerated by materials which exhibit exothermic behavior in the presence of water. Such polymerizable compositions are suitable as mortar compositions for fastening anchor rods.

Compositions which set in the presence of water, their use and method

Cycloaliphatic compounds, which have one or more ethylenically unsaturated substituents, are disclosed as components of borehole-filling masses, optionally together with other curable components.
