GÓRKAL 50+

Application
foto worka górkal 50+
  • Low content Fe2O3
  • Fast increase in mechanical strength
  • Short setting time

Thanks to it's stable phase composition, GÓRKAL 50+ has excellent mechanical properties, can be used in mortars and concretes in construction chemicals, and may be an insulating component of refractory compounds or other jointless materials.

GÓRKA cement offers an attractive alternative to GÓRKAL 50+, well known to our customers GÓRKAL 50 with increased content of Fe2O3.
