Abstract

An anchor assembly includes an anchor bolt or stud and an adhesive material for securing the bolt in a prepared borehole. The adhesive material consists of at least two required components which, when mixed together, harden to fix the bolt within the borehole. Of the two required components, one is located within a cartridge and the other is placed on the shank of the anchor bolt and can be enclosed within a destructible sheath. By driving the bolt into the cartridge the components are mixed. Either a mixture promoting material can be included in the cartride or mixture promoting members can be associated with it to assure the component is stripped from the bolt and adequately mixed with the component in the cartridge.
