Microsilica, also known as silica fume, is a by-product generated during the production of ferrosilicon or industrial silicon. Its ultra-fine particles and high reactivity make it an excellent supplementary material in concrete, where it enhances strength, durability, and overall performance. It is widely used in applications such as high-performance concrete, refractory materials, and various industrial products.

Incorporating microsilica into concrete can significantly improve its mechanical properties. It enhances compressive strength, reduces permeability, and improves durability, leading to longer-lasting structures. This can result in lower maintenance costs and improved resistance to chemical attack, making it particularly beneficial for infrastructure projects like bridges and high-rise buildings.

The selection of the appropriate grade of microsilica depends on various factors, including the desired performance of the concrete, the target compressive strength, workability requirements, and specific parameters such as loss on ignition and particle size distribution. Our product range is categorized by these key specifications, and we provide detailed technical data to help you select the most suitable grade for your needs.

Microsilica is used in a variety of applications including high-performance concrete, self-compacting concrete, and ultra-high-performance concrete. It is also utilized in refractory materials, ceramics, rubber, and coatings. Its unique properties help to enhance durability, reduce permeability, and improve overall material performance in these applications.

By partially replacing cement in concrete mixes, microsilica reduces the overall cement content, which in turn lowers CO2 emissions associated with cement production. Additionally, its use promotes the recycling of industrial by-products and supports the circular economy by transforming what was once considered waste into a valuable resource for construction.

While specific quality standards may vary among suppliers, high-quality microsilica typically meets established industry standards regarding particle size, reactivity, and chemical composition. Detailed technical data and test results are usually provided to ensure that the product performs as expected in various applications.

Microsilica is transported in bulk, supporting container and ton bag shipments, and also supports sea transportation. And we can support large orders; handling several thousand tons is not a problem.

Yes, microsilica can be used alongside other supplementary cementitious materials (SCMs) such as fly ash, slag, and natural pozzolans. When combined appropriately, these materials can synergistically enhance the performance of concrete by improving workability, strength, and durability.
