Abstract
A multi-component inorganic capsule anchoring system, for chemical fastening of anchors and post-installed reinforcing bars in mineral substrates, includes a curable powdery aluminous cement component A and an initiator component B in aqueous phase for initiating a curing process. The powdery aluminous cement component A is an aluminous cement component based on powdery calcium aluminate cement, and component B includes an accelerator constituent and water. A method can be utilized for chemical fastening of an anchor, such as metal anchors and post-installed reinforcing bars, in mineral substrates, such as structures made of brickwork, concrete, pervious concrete, or natural stone.
Claims18
A multi-component inorganic capsule anchoring system for chemical fastening of an anchor or post-installed reinforcing bar in a mineral substrate, comprising:
- a curable powdery aluminous cement component A in a first chamber of the multi-component inorganic capsule and an initiator component B in an aqueous-phase in a second chamber of the multi-component inorganic capsule for initiating a curing process,
- wherein the powdery aluminous cement component A comprises an aluminous cement component comprising powdery calcium aluminate cement, and
- wherein the initiator component B comprises an accelerator and water.
