Bulk Cement

Bulk Cement

We utilize the modern technology lines & materials in the best way. Long Son Clinker & Cement Products have high quality, content of hazardous impurities such as MgO & total low alkalinity (R2O). Our products meet all the most severe technical requirements of Vietnam standards & International Standards ASTM, BS EN.

Advantages of Long Son Industrial Cement Products PC50 & PCB 40: Having an excess of high grade and stable quality. Therefore, by using Longshan Cement Products, the concrete mixing plants will save the amount of used cement and stable-quality concrete products in accordance with design standards.


  • PC50 & PCB40 Industrial Long Son Cement has high early strength (R3 & R7), which enables to push up the construction progress and save construction costs.
  • Time for cement setting process of Long Son Cement products are prolonged, which ensures time to deliver the commercial concrete to the far projects.
  • The content of free lime & low MgO in the cement is low (<1%), therefore, its volume isn’t expanded after construction and there’s no cracking phenomenon of concrete products using Long Son cement after being taken into use.
  • Total R2O alkali content in cement is very low (<0.5%) , which eliminates the causes of corrosion & demolition of concrete structure and increases the sustainability of concrete.
