Pozzolanic cement
It is made by grinding some solidification regulator (gypsum) with Portland cement clinker and mineral additives (pozzuolana) defined at their standardized ratios (max. 55%).
It is a product that gains its strength by freezing after it is mixed with water.
It gains strength later than Portland Cement 42.5 and Portland Composed Cement A 42.5 R.
Water/cement ratio is relatively high.
It is more resistant to alkali-aggregate reaction and chemical external effects.
Generally it is used in the repairs of constructions, making plaster and production of construction chemicals.
