DG Cement's Sulphate Resisting Cement (SRC) is more resistant to Sulphate attacks and is suitable for use in foundations near seashore and canal linings where relative risks of sulphate expansion is present in the structures.

LOW C3A CONTENT

Sulphate salts present in some soils 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.
