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.
