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%.
