CL-90 microsilica powder – raw ash
Microsilica CL90 is a supplementary cementitious material, comprising of amorphous silica produced by electric arc furnaces as a byproduct of the production of elemental silicon or ferro silicon alloys and selected additives.
Microsilica CL90 can be used in a variety of applications, such as concrete, mortars, grouts and fiber cement products.
Microsilica CL90 is delivered as a bulk materials in tankers ready for rapid, direct discharge into microsilica silos.

Product Description: Micro-silica powder, also referred to as “Silica Ash,” “Microsilica,” or “Silica Fume,” is an amorphous form of powdered silica (SiO₂). It is collected through a specialized dust collection system following the oxidation of silicon vapor emitted during the smelting process of ferrosilicon and industrial silicon. The average particle size of micro-silica powder ranges from 0.1 to 0.15 μm, which is approximately one-hundredth the size of typical cement particles. With a specific surface area of 15-27 m²/g, it exhibits highly active surface properties.
Applications: Micro-silica powder is widely used in various applications, including high-strength concrete, amorphous refractory materials, dry-mix (ready-mix) mortars, high-strength non-shrink grouting materials, wear-resistant industrial floors, repair mortars, polymer mortars, thermal insulation mortars, impermeable concrete, self-leveling concrete, concrete compaction agents, concrete preservatives, and cement-based polymer waterproofing agents. Additionally, it is utilized for reinforcing rubber, plastic, unsaturated polyester, paints, coatings, and other polymer materials, as well as for modifying ceramic products.
