Micro Silica Fume Powder, Packaging Size: 25 kg

Micro Silica Powder, also known as Silica Fume, is an ultra-fine amorphous form of silicon dioxide (SiO₂), produced as a by-product of the silicon and ferrosilicon alloy industry. It is widely used as a mineral admixture in high-performance concrete to improve mechanical properties and durability by refining the pore structure and reducing permeability.Key Features: Extremely fine particle size (average diameter < 1 micron) Contains over 90% reactive amorphous silica Enhances compressive, tensile, and flexural strength Reduces chloride ion penetration and permeability Improves sulfate and chemical resistance Excellent pozzolanic reactivity Applications: High-performance and high-strength concrete (HPC & HSC) Marine and bridge structures Industrial flooring and precast elements Shotcrete and tunnel linings Oil well grouting and repair mortars
