Advantages
: significant increase in mechanical resistance, notable reduction in chloride penetration and carbonation, significant increase in electrical resistivity with consequent high anti-corrosion power.

Consumption
: 5-15% of the weight of the cement.

Packaging
: Big bag 1,200 kg; Bags 10-25 kg.
