Product Description:

MICRO SILICA

Micro Silica  is an ultra fine powder and is light to dark grey in color. It has high strength & density in concrete and it also prevents bleeding and Segregation in fresh concrete. It has low permeability and water tightness.
Used for :

• High performance concrete
• Precast concrete
• Dry and wet shot Crete
• Underwater concrete

ADVANTAGES :

• Increased Strength and density in concrete
• Prevents Bleeding and segregation in fresh concrete
• Low Permeability and water tightness
• Resistance to Chlorides and Sulphates
• Corrosion protection
• Better flexural strengths at all ages
• Excellent Freeze /thaw resistance
• Abrasion and erosion resistance
• Dramatically improved durability

BRIEF SPECIFICATIONS:

• High strength
• Acid & chemical reaction : 10 – 15%
• Alkali silica reaction 10 – 20%

RATE OF ADDITION :Micro Silica is recommended for use at an addition rate of 5 to 15 % by weight of cement depending on the application. The exact amount for strength or durability requirements should be determined on case to case basis by conducting trials for the specific projects.
