Dalton Micro Silica

Micro Silica is ultra fine amorphous (non-crystalline) polymorph of silicon dioxide. Because of its extreme fineness and high silica content, silica fume is a highly effective pozzolanic material. Silica fume is used in concrete to improve compressive strength, bond strength. It is highly resistive to impact, abrasion, heat and chemical attacks.  It also reduces permeability; and therefore helps in protecting reinforcing steel from corrosion.

Advantage

• Reduces thermal cracking caused by the heat of cement hydration
• High Strength Concrete
• Waterproof Concrete
• Improves durability to attack by sulphate and acidic waters
• Reduces the early age temperature rise
• Silica fume is cheap; therefore, it is cost-effective
• It reduces the overall slab weight and cost

Specification

• Silica Content  : 80-95%
• Moisture Content : Max 1%
• Loss on Ignition : Max 5%
• Bulk Density: 600-650 Kg/m3
