Abstract:
A method of making chemical anchoring adhesive, comprising the steps of:providing a borehole having a depth D, an apparent volume V1, and an average cross-sectional area A1; providing an anchor pin having a portion extending into the borehole, the portion in the borehole having an average cross-sectional area A2 which is smaller than A1, and an apparent volume V2; determining a volume VA of chemical anchoring adhesive required to fill an interstitial space between the anchor pin and an inner wall of the borehole when the anchor pin is driven into the borehole; determining a desired cross-sectional area A3 for the anchoring adhesive from the volume VA; and preparing a rope or slug of the anchoring adhesive having the desired cross-sectional area.
