A chemical anchoring adhesive includes first and second parts each having a highly viscous, putty-like consistency. The first and second parts are joined directly to each other along an interface. Desirably, the first part includes about 20 - 45% by weight of an epoxy resin, about 10 - 40% by weight of a first particulate filler having an oil absorption value of at least about 30 and about 40 - 65% by weight of a second particulate filler, at least about 70% of which has a U.S. sieve size between 16 and 45. Desirably, the second part includes about 5 - 20% by weight of an aliphatic amine compounds about 0.1 - 15% by weight of a tertiary amine compound, about 1 - 23% by weight of a first particulate filler having the oil absorption described above and about 52 - 87% by weight of a second particulate filler having the U.S. sieve size described above. The anchoring adhesive does not require separate encapsulation of one or both parts and can be formed and cut to desired sizes and quantities at any stage before insertion into a borehole.
