High ACTIVE META KAOLIN KAOPOZZ
    High active metakaolin KAOPOZZTM is made of high quality kaolinate.The metakaolin is calcined under precisely controlled temperature.With high pozzolana reactivity,it can increase the strength and obdurability of cement and concrete.It's particularly applied for poly cement,high strength concrete manufacturing.It's applied to the construction of bridge,dock,dam,mansion,highway,and etc.

  A:Test with GB/T 18736-2002 "Mineral Added in High Strength and Property Concrete". Replace 10% cement with KAOPOZZTM.The water cement ratio is 0.5-0.55.When add water reducing agent,the water cement ratio will be lower,and the activity index will be higher.
  B:Test according to Chapelle.
