Nano Silica in Concrete and Cement Industry (NTS550)

Nano silica, a very fine and reactive additive, plays a significant role in improving the properties of concrete and mortar. By altering the microstructure of concrete, this material enhances its mechanical properties, durability, and workability.

Role of Nano Silica in Concrete and Cement Industry including

• Increased Compressive and Tensile Strength: Nano silica fills the micropores in concrete, increasing its density and consequently improving its compressive and tensile strength.
• Reduced Permeability: Nano silica blocks the pores in concrete, reducing its permeability to water, chloride ions, and other harmful substances. This is particularly important for concrete exposed to corrosive environments.
• Increased Durability: Reduced permeability of concrete increases its durability against destructive environmental factors such as freeze-thaw cycles, wet-dry cycles, and sulfate attack.
• Improved Workability: Silica increases the workability of concrete and reduces the water-to-cement ratio, which in turn increases the strength and durability of concrete.
