Synthetic gypsum

The EKO-ZEC company introduces the synthetic gypsum from the Kozienice Power Plant (ENEA Wytwarzanie Sp. z o.o.) to the market under the trade names of:

  • "kruszywo wypełniające ER Gips" ("ER Gypsum filling aggregate") intended for use as aggregate in accordance with IBDiM (Road and Bridge Research Institute) Technical Approval;
  • "REA-GIPS" ("FGD-GYPSUM") intended for the manufacture of clinker for cement production and for the manufacture of plasterboards and other construction materials.

In accordance with the IBDiM (Road and Bridge Research Institute) Technical Approval No. AT/2016-02-3219 The ER Gypsym EKO-ZEC filling aggregate is intended for use in communication engineering (road) for aggregates, soil and binder mixtures. Thanks to its chemical and mechanical properties, it adjusts the properties of mineral compounds as an additive improving and correcting the grain size.

ER Gypsum EKO-ZEC filling aggregate can be used for:

a) creating embankment layers,

b) as a compound increasing the gradation of the mineral mixture:

  • in the auxiliary foundation layers (frost protection, shut-off and reinforcement layer) acc. to the requirements of WT-4 2010 or according to the requirements of PN-S-06102:1997, when using the mechanical stabilisation technology
  • in the auxiliary foundations, acc. to the requirements of WT-5 2010 or according to the standards for mixtures of aggregates or soils stabilised with binders

c) for the enhanced soil, acc. to the requirements of WT-5 2010 or according to the standards for mixtures of aggregates or soils stabilised with binders
