Here it can replace about *0% of clinker. Natural Pozzolana can also be ground finely by itself to say 4, **0 Blain and used directly in the cement concrete mix where it can substitute cement. Substituting *0% Portland cement with fine natural pozzolana will accomplish the following: 1. Lithification 2. Autogenous healing 3. Improves Fatigue properties 4. Reduces permeability and voids 5. Reduces expansion and heat of hydration 6. Reduces creep and cracks 7. Reduces micro-cracking 8. Increases compressive strength 9. Increases resistance to chloride *0. Increases resistance to sulfate attack *1. Reduces alkali-aggregate reaction *2. Impedes carbonation *3. Reduces freeze-thaw damage *4. Protects steel reinforcement from corrosion *5. Increases abrasion resistance *6. Lowers water requirement with high fluidity, self-leveling and self-compression *7. Improves durability *8. Reduces costs of production and construction *9. Increases production capacity and reduces energy requirements and costs *0. Reduces carbon dioxide emissions *1. Unifies quality Specifications HIGH QUALITY NATURAL POZZOLANA FOR USE AS SUBSTITUTE FOR CLINKER (UPTO *0%) IN BLENDED CEMENT.
