Abstract

The cartridge comprises a frangible outer tubular casing (14) fabricated of plastic or the like and containing a uniform mixture of a water-hardenable cement (15) and a multitude of frangible microcapsules (16) which hold droplets of water. One or more of these cartridges is placed in the borehole (12), and the anchor element (11) in a one-step operation is inserted therein, and preferably rotated, to pierce the casing (14) and rupture the micro-capsules (16) to uniformly wet the cement to form a cement paste. Example filling comprises 66% Alpha gypsum cement, 1% K2SO4, 33% microencapsulated water. <IMAGE>
