Akij Portland Cement – OPC

Ordinary Portland Cement (OPC) - Type CEM-I

Akij Type- I or Akij Portland Cement known as Akij OPC is a general purposed cement used for all general construction viz high rise Building etc. especially for precast or pre-stressed concrete with more than 95% high quality clinker having greater than 60 % Tri Calcium Silicate (C3S) offers early set and boost up the compressive strength more than desired level.

Field of Application

  • Structures & Monolithic or Prefabricated Elements.
  • Concrete Foundations.
  • Concrete for Massive structures
  • All kinds of Reinforced & masonry work.
  • Concrete with High resistance to chemical Attack
  • Mass Structures such as large pier, heavy abutments & Retaining Wall.
  • Brick-laying & Plastering Mortars
  • Drainage Structures which are subjected to moderate sulphate concentration from ground water.

Getting High Early Strength

Akij Portland Cement with higher percentage of Tricalcium Silicate (C3S), Dicalcium Silicate(C2S),& Tricalcium Aluminum Ferrice (C4AFe) & exhibit this high early strength. It hardens rapidly and mostly responsible for initial setting time. Akij PC shortens your project duration & reduces projects cost. Pre-stress work can be done with scheduled project duration.

Setting Faster

Setting Faster helps to set the concrete quickly even in low temperature & also be during rainy seasons. Presence of Tricalcium Silicate (C3S), Dicalcium Silicate(C2S),& Tricalcium Aluminum Ferrice(C4AFe) in AKIJ ORDINARY PORTLAND CEMENT hydrens quickly .It also reduce amount heat generate & getting faster setting on behalf of this unique chemical compositions.

Anti-Cracking & Shrinkage

It is most difficult to control inner temperature of mass concrete between surface temperatures during its hydration process. These unbalanced temperatures may create “Thermal cracks”.Akij Ordinary Portland cement contains unique chemical composition that’s why it resist cracking & when proper consistency of concrete maintain at construction level with others additive measures shrinkage can be minimized.
