Long Son PC Cement is produced according to American standards ASTM C 150 – Type I for export to foreign markets. With high quality PC Cement is produced by grinding clinker and a certain amount of gypsum to ensure setting time.
Long Son PC Cement uses raw materials from the best rated raw material areas in Vietnam combined with Japanese technology, under the management of experienced experts. The ratio of ingredients in PC cement ensures compliance with customers’ diverse construction requirements. The main ingredients are Portland clinker accounting for 95 – 96% and gypsum accounting for 4-5%.
PC cement can be used for many construction items or used to produce concrete for bridges, culverts, prestressed concrete, hydroelectric dams or high-rise buildings.
Advantages of Long Son PC cement:
– High initial strength development speed helps quickly remove formwork early
– High stability, good waterproofing and not corroded by the environment
– Cement can use additional water-reducing additives so it is easy to use and control concrete quality in special projects.
