  • Ultra Fine Cement. (Fineness is exceptionally higher due to the use of more Fly Ash content)
  • It can gain Strengths for longer period of time.
  • It exhorts higher efficiency even applied with lower water.
  • It requires lesser water so it’s concrete will produce higher strength.
  • It protects concrete from Sulphate, Chloride and other chemical attacks. Also protects the Reinforcements from rusting.   
  • During Hydration it produces lesser heat as a result lesser cracks are formed in the surface of the concrete.
  • The surfaces of the concrete remain smoother.
