mineral grinding sulphate resistance

Sulphate Resistance of Geopolymer Concrete Prepared
The compressive strength of geopolymer concrete when exposed to a 5 sodium sulphate solution for more than 1 year was superior to that of OPC concrete These materials could be used for making sulphate resistant concretes attributable to a more stable cross linked aluminosilicate polymer structure formed in the geopolymer concrete.
