PORTLAND CEMENT CEMI 52.5R

BS EN 197-1 CEM I 52.5R

Ordinary Portland cement is a product which is obtained as clinker resulting from mixing at suitable rates, grinding and firing raw materials such as limestone, marl, clay, iron ore, pyrite ash, bauxite, etc. and a certain amount of setting regulator (generally gypsum) are ground together and sets after mixing with water and gains strength.

Application:

  • Used in works requiring high strength values
  • Dam and tunnel works
  • Precast building and concrete works in low temperatures
  • Construction chemical production
  • Foundation application
