Portland Composite Cement-PCC

Portland Composite Cement (PCC), Type CEM II/B

Akij Type- II B or Akij Portland Composite Cement known as Akij PCC continues to gain strength due to its Iron slag even after 91 Days. It’s C-S-H gel coats the bar to protect against corrosion, reduce permeability & void ratio to make Durable concrete or Dura-crete, enhance the life cycle of the structures. With added Limestone smooth plastering makes the structures Fair-Facing.
