Abstract
A multi-component inorganic capsule anchoring system can be used for chemical fastening of anchors, bolts, screw anchors, screw bolts, and post-installed reinforcing bars in mineral substrates. The multi-component inorganic capsule anchoring system contains a curable powdery ground-granulated blast-furnace slag-based component A, and an initiator component B in aqueous-phase for initiating the curing process. The powdery ground-granulated blast-furnace slag-based component A contains further silica dust. The component B contains an alkali- or alkaline earth-hydroxide, alkali- or alkaline earth-carbonate, or alkali- or alkaline earth-sulfate component.
Claims20
A two-component inorganic capsule anchoring system for chemical fastening of anchors, bolts, screw anchors, screw bolts, and post-installed reinforcing bars in mineral substrates, comprising:
- a curable powdery ground-granulated blast-furnace slag-based component A, and
- an initiator component B in aqueous-phase for initiating a curing process,
- wherein the powdery ground-granulated blast-furnace slag-based component A comprises silica dust,
- wherein component B comprises an alkali- or alkaline earth-hydroxide, alkali- or alkaline earth-carbonate, or alkali- or alkaline earth-sulfate component,
- wherein components A and B are present in a capsule and are separated within the capsule to inhibit reaction between components A and B,
- wherein the capsule is a two-component inorganic plastic or foil capsule that is a capsule-in-capsule or foil-in-foil system,
- wherein the A and B components are kept separate by walls or foil bags,
- wherein components A and B react during the chemical fastening, and
- wherein component B does not contain a filler.
A two-component anchoring system, comprising:
- a curable powdery ground-granulated blast-furnace slag-based component A, and an initiator component B in aqueous-phase for initiating a curing process,
- wherein the powdery ground-granulated blast-furnace slag-based component A comprises silica dust, and
- wherein component B comprises an alkali- or alkaline earth-hydroxide, alkali- or alkaline earth-carbonate, or alkali- or alkaline earth-sulfate component,
- wherein components A and B are present in a multi-chamber device and are separated within the device to inhibit reaction between components A and B,
- wherein components A and B react during the chemical fastening, and
- wherein the multi-chamber device is a plastic capsule-in-capsule or foil-in-foil, system, and
- wherein component B does not contain a filler.
