An improved hardenable inorganic grouting composition comprising (1) a dry inorganic cement powder, (2) liquid containing capsules, and wherein the liquid is reactive with the inorganic cement, and wherein the capsules are pressure sensitive and capable of being progressively ruptured by the force of the anchor element, and (3) a small amount of a lubricant in such form and amount to allow the cement powder and the capsules to flow as free flowing solids. This grouting composition is preferably in the form of a cartridge having an elongated tubular casing. |
