Abstract (en)
A grouting composition for anchoring a reinforcing member in a hole is delivered into the hole in uncartridged, unmixed form. In the hole the reactive components of the grout are present in stable, minimally interpenetrated adjacent columns (3, 4) of fluent material adapted to remain in position in a vertical, overhead hole. When convenient, the reinforcing member is inserted into the columns of material and rotated, whereby the mixed material hardens. The stability of the grout after delivery to the hole frees the user from tight time constraints on the placement of the reinforcing member therein.
