ORDINARY PORTLAND CEMENT

Exceptional Strength
To ensure that cement dispatched to customers is with Zero defect quality and have exceptionally high strength superseding national and international standards, automatic quality control is done through online X-ray analyzer and computer controlled systems. Our focus is not only on the quality of cement dispatched but on the consistency of the high quality cement dispatched. We may further add that the Quality Control department carries out regular checks and analysis of various raw materials, intermediate products and final products in order to have additional quality checks. At DGKCC the chemical composition and grinding fineness are closely monitored to ensure that both Pakistani and British standards are surpassed and our customers get cement of exceptional strength.

Ideal Setting Time
In order to allow sufficient time for application, cement must have a quick initial settings time. However once in place, the final settings should not take too long. At DGKCC ideal initial and final setting times are maintained.


SULPHATE RESISTANT CEMENT

Low C3A Content
Sulphate salts present in these soil combine with moisture and tri-calcium aluminate (C3A) , one of the constituents of cement to form a compound known as Sulpho Aluminate off Hydrated Calcium. This compound is highly expansive and gradually results in the destruction of concrete. However, if a C3A content is very low, it is rendered inert and there is thus no reaction at all. British and Pakistani standards specify that in a Sulphate Resistant Cement, the C3A content must not exceed 3.5%. D.G Sulphate Resistant Cement has a much lower C3A content, making the cement highly effective against Sulphate attacks

High Strength
As with any type of cement, strength is the fundamental property of Sulphate Resistant Cement D.G. Sulphate Resistant Cement achieves high strength through finer grinding and better particle distribution. In term of strength,, it not only exceeds by far the standards specified for Sulphate Resistant Cement, but also exceeds those of Ordinary Portland cement

Low Alkali Content
Certain aggregates contain alkali sensitive ingredients, which under unfavorable conditions, can result in expansion leading to cracking of concrete. The presence of alkali also causes staining and other undesirable effects on concrete. American Standards specify that cement can be termed low-alkali if its alkali content does not exceed 0.6%. D.G. Sulphate Resistant Cement has alkali content below 0.6 and a unique distinction of being a Sulphate Resistance Cement that can also be classified as low - alkali cement.

QUALITY CONTROL

DGKCC is also practicing best quality control procedures to maintain and enhance the quality of not only products but also its operations for following purposes:

  • To exercise complete control over the production Process, Inspections and Tests, and also over the financial work flow like Purchase, Sales, Inventory, Delivery.
  • To optimize production of cement while maintaining the product quality standard all the time with due consideration to cost factor and environment.
  • To maintain the plant, machinery and equipment in the best condition to avoid any breakdown or error in process.
  • To ensure that all employees are aware of their responsibilities and are adequately qualified to carry out their duties most effectively.
  • To carry out planned audits and reviews to ensure effective implementation and continued suitability of this policy, to revise or modify it if necessary and ensure continual improvement of the quality system.
