Corrosion Resistant

In hydration process, Portland Slag Cement reacts with water and calcium hydroxide Ca(OH)2 to form additional CSH gel. CSH is the glue that provides strength and holds concrete together with reinforcement [Rod] and resulting in lower permeability.Lower permeability reduces chloride-ion and other air access to the RCC and thus reduces the corrosion of inner structure.

Higher Strength

Clinker is the basic raw material of cement. When slag is used as a part of cementitious material in a concrete mix, it reacts with water and Ca(OH)2 to form more Calcium Silicate Hydrate (CSH) gel. CSH is the glue that provides strength and holds concrete together. The additional CSH densifies the concrete matrix and enhances strength. Usage of 65-79% clinker in Diamond Coastal Plusand its additional CSH gel from Slag, increases 15% more strength in 91 days than other cements.

Anti Crack

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”. Diamond Coastal Plus can mitigates this high inner temperature by producing more CSH gel and reduce the possibility of thermal cracks.

Damp Proof

Blast Furnace Slag is a calcareous and alumino-silicate compound like Clinker. It does not contain carbon; so that it has no ability to attract moisture and hence there is no chances of dampness of concrete structure.

Appearance

In contrast to the stony grey of concrete made with Portland cement, the near-white color of Slag cement permits architects to achieve a lighter color for exposed fair-faced concrete finishes, at no extra cost. To achieve a lighter color finish, Slag is usually specified. Slag cement also produces a smoother, more defect free surface, due to the fineness of the Slag particles

Application

• Mass Concrete Foundations,Waterdam,Reservoirs or any other hydraulic structure which require low heat of hydration.
• Marine Concrete Structure exposed to Sea Water & Sulphates.
• Bridge, Jetty, Bored Piles& any other submerged structure in coastal zone.
• Concrete which may consist of Alkhali reactive aggregates.
• High strength Pre Cast & Pre stressed concrete.
