Building material systems for mining application

Services

Development and supply of a broad range of products of special mortars, building material systems and special products for mining application predominantly in saline formations with defined characteristics:

Building material systems for saline application

Building Material	Application
Mortar for instrumentation and embedding	Fine-grained, pumpable over long distances mortar for the frictional connection of measuring devices to the surrounding rock and to the building structure
Fixing mortar	Mortar pumpable over long distances fixing the position of measuring devices or armatures with low heat effect when setting and reduced one-axial strength
Backfilling building material	Free-flowing, self-levelling building material for filling of boreholes, fissures and other cavities
Injection mortar	High-tight, load reducing injection mortar to seal fissures and gaps with a volume expansion up to 10 % in a not restrained state
Systems for construction of dams and barriers	High-tight, load reducing building material systems with a limited behaviour of compaction used for sealing of buildings in the rock salt, hard salt or Carnallitite; adjustable to the specific situation
Mixtures of building materials for immobilization of solutions rich in MgCl2 und CaCl2	Conversion of solutions rich on MgCl2 and CaCl2 (contaminated solutions too) with low addition of binders in a permanently flexible, stationary body

Special products

Development and supply of patented Mg-depot systems for the CO2 immobilization in underground cavities.
