Vicem Ha Tien Portland Cement PC50 is a fine powder mixture of various minerals. It is produced by mixing calcareous minerals such as limestone, clay containing silica and alumina and heating it to 1450 °C. When it cools, a clinker is formed. This clinker is then finely ground and mixed with a small quantity of 3-5% of gypsum, which has calcium sulfate in it. The amount of gypsum controls the physical properties of the eventual cement and concrete.
USES
PC or OPC is a general-purpose cement suitable for all uses, especially for industrial and civil constructions requesting high strength. This type of cement can be used to make concrete for bridges, culverts, reservoirs, reinforced concrete,...
