Product details


Microfine portland cement is a type of cement that has very fine particles and a high specific surface area. It is used for grouting applications in rock and soil injection, where it can penetrate into tight joints, fissures and pore spaces, and provide a watertight and durable seal. Microfine portland cement can also improve the strength and stability of the grouted mass, and resist chemical attacks and corrosion.

There are different grades of microfine portland cement available in the market, depending on the fineness and the setting time. One of the common ways to measure the fineness of cement is by using the mesh size, which indicates the number of openings per inch of a sieve. The higher the mesh size, the finer the cement particles.



  • Improve the strength and stability of the grouted mass
  • Resist chemical attacks and corrosion
  • Nontoxic and environmentally friendly
  • Controlled setting time and can be adjusted with admixtures
  • Compatible with most admixture types
  • Superior sulphate and chloride resistance compared to ordinary Portland cement

Applications Filed

  • Stabilize weak soils: Filling in the voids between the soil particles, makes the soil stronger and less collapse.
  • Rock injection: Seal weepingleaks in dams, caverns, mines and tunnels etc.
  • Pre-/post- grouting: For all underground structure excavation
  • Curtain grouting: Seal cracks and voids quickly and effectively.



Kangjing’s microfine portland cement has a shelf life of six months when stored in sealed bags, kept dry and out of direct sunlight.



Kangjing supplied in 20 kg bags, 25 kg bags or 1000 kg bags.
Any other option can be customized


Pot Life

The mix should be kept under constant agitation prior to injection. Do not keep mix in agitator longer than 30 to 40 minutes.
