Form-stable blocks for sealing distances in salt rock, has casting sand mastic asphalt of such texture that compound assembly is monolithised to sealing element from these blocks at location under influence of pressure and heat

摘要

The blocks has a casting sand mastic asphalt of such a texture that compound assembly is monolithised to a sealing element from these blocks at the location under influence of pressure and heat. The sand mastic asphalt consists of an oxidized bitumen as an adhesive agent with a high penetration index, a softening point and a needle penetration. Independent claims are also included for the following: (1) a method for the installation of form-stable blocks (2) an assembly for sealing distances in the salt rock.
