                                                         PARASIL (Micro Silica)
Description :-
PARASIL is a fine powder Micro Silica which has great Pozzolanic properties. It is aby-product material which consists of non-crystalline silicon dioxide with high specific surface area andhigh pozzolanic reactivity.

Workability :-

Water demand and workability of the concrete are significantly influenced by particle sizedistribution.present in the solid system. Typical concrete mixtures do not have an optimum particle sizedistribution, and this accounts for the undesirably high water requirement to achieve certain workability. Toplasticize a cement paste for achieving an acceptable consistency much larger amounts of water thannecessary for the hydration of cement. However, there is the possibility of water reduction higher than 20%in case of the use of our Micro Silica. This is because fine particles of our Micro Silica get absorbed on theoppositely charged surfaces of cement particles and prevent them from flocculation. The more the fineness the more is the numberof contacts among the particles and hence the more is the resistance to flow.

Water absorption :-

One of the main sources of contamination of concrete in structures is water absorption which influencesdurability of the concrete and also has the risk of alkali aggregate reactions. The more impermeable theconcrete, the greater will be its resistanceto deterioration. The use of our product in the composites couldcause an extensive pore refinement in the matrix and in the interface layer, thereby decreasing waterpermeability. The permeability willdecrease rapidly with the progress of the hydration, Our product moreeffectively block the pores helping to reduce permeability.

Compressive strength :-

Normally use of our Micro Silica in the below mentioned percentages enhances the compressive strength.10% to 15% - High strength structural columns10% - Flatwork8% to 10% - High durability / Low permeability such as bridge decks or parking structures8% to 15% by weight of cement, but as addition not replacement.Note:- The usage will absolutely depend upon the requirement of the quality of the concrete as per therequirement of the Customer.Moreover, using 30% of our product could be considered optimum for all content of W/C ratios ininvestigated concrete because of its high value of compressive strength. Use of our product could help toachieve higher compressive strength and decrease of permeability due to reduced porosity, reducedcalcium hydroxide content and reduced width of the interfacial zone in the aggregate. 
Durability properties of concrete containing our Micro Silica :-

Alkali-silica reaction :-

Our Micro Silica is used to prevent or minimize cracking in concrete due to the expansive gel formed bythe alkali—silica reaction.

Chloride-ion diffusion :-

It is approved that the long term deterioration of concrete and corrosion of reinforcing steel commonlyoccurs by entrancing the chloride ions into body of concrete structures. It is also well known that the rate ofchloride ion diffusion into concrete is related to the permeability and pore size distribution. The ability of our
Sulfate resistance :-

Concrete mixed with our Micro Silica has good resistance to sulphate attack.
