Portland cement (PC cement) is manufactured under the American Standard ASTM , BS EN or GB/T served the purpose of export to foreign markets. Portland cement is produced by grinding clinker and a certain amount of gypsum to ensure the setting time.

CEMENT 42.5R / CEMENT TYPE I / CEMENT TYPE IP / SLAG CEMENT: Cement production 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.


PC cement uses raw materials of an area which is evaluated as the best material area in Vietnam combined with Japanese technologyunder the management of experienced specialists. The ratio of Portland cement components is ensured to be appropriate with diverse construction requirements of customers. Major components are Portland clinker with the proportion of 95-96% and gypsum with the proportion of 4-5%.

PCB30 Cement


Portland Cement Blended PCB 30, MC25 branded LS helps to increase the flexibility of mortar, waterproof, impregnation to environment; strengthen the lifetime of constructions, and is very suitable with the tropical climate conditions of Vietnam



Advantages of Portland Cement Blended PCB 30, MC25 branded LS • Quality of cement is always ensured to be stable. Especially, cement compressive strength is always in over-graded rate that is an advantage to consumer

Portland Cement Blended PCB 30, MC25 branded LS has high fineness to develop the compressive strength earlier and has high detention capacity to enhance flexibility of concrete and mortar helping the finishing easier without cracking phenomenon of plaster coat.

The content of free lime and MgO in cement is low, so it’s not be expanded after the construction. Products from concrete and mortar using LS cement will have no shattering sign of concrete block & block wall texture after putting into use. The content of total alkali R2O in cement is very low <0.5%, so it eliminates the causes leading corrosion & demolition of concrete and wall structure for works)
