Abstract

1275941 Unsaturated polyester resins F SCHUERMANN and A JANKOWSKI 11 Aug 1969 [10 Aug 1968] 40051/69 Heading C3P [Also in Divisions E1 and F2] An anchor rod is secured in a hole in soft rock by providing two resin/hardener mixtures in the hole, one mixture having a greater hardening time than the other and comprising, as an example, polyester resin, an accelerator and powdered stone in one frangible compartment and hardening powder (e.g. benzoylperoxide in gypsum paste) in another frangible compartment of a breakable container.
