LS Portland cement (PC cement) is manufactured under the American Standard ASTM C 150 – Type I 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.
LS 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%.
Portland cement can be used for many work items or used to manufacture concrete for construction of bridges, culverts, prestressed concrete, hydroelectric dams and buildings.
Advantages of LSC Portland cement:
– High initial strength growth rate helps remove the formwork soon.
– High stability, good antileakage capacity and no corrosion by the environment
– Cement can use water-reducing additive, so it’s very easy to use and control the quality of concrete in special buildings.
