Understanding Micro Silica And Its Manufacturing Process: A Complete Guide

Micro silica, or silica fume as it is commonly referred to, is widely used modern construction and industries in general. Due to the trends exhibited in the construction sector, micro silica manufacturers have gain a central root into the construction industry especially in the production of high performance concrete and other specialized products.

What is Micro Silica?

However, it is important to know what micro silica is, before dissection on the process of manufacturing deeply. This is an ultrafine powder constituted by spherical particles that are about one-hundredth times that of cement size. It is recovered as a co-product of the production of metallic silicon and ferrosilicon alloys in electric arc furnaces.

Manufacturing Process

Micro silica manufacturing involves a process that is extremely controlled. Major steps include

• Collection Phase: In the production process of silicon metal, silicon dioxide vapor is formed. The vapor rises further and cools to form small spherical amorphous silica particles. Special collection systems are used to trap these particles before they become part of the atmosphere.

• Filtraion: The collected material would go through advanced filtraion systems to ensure that it meets all quality parameters, in addition to proper particle size. Well-established micro silica manufacturers spend significant amounts on this stage to ensure product quality.

• Processing and Testing: The extracted material is then processed and checked through several processes for quality and consistency. Producers check chemical content, size, and other attributes for quality against industry norms.

• Packaging: The product is carefully packed in any one of three forms - densified, undensified, or slurry form, based on customer need and transport mode.

Players in the Industry

There are many micro silica producers all over the world, and they may vary in size. Large scale producers usually are near the silicon metal fabrication factories while mid and small scale manufacturers may specialize on refining and marketing. Specialty products have also been introduced in many manufacturing companies that indicate specialization of the industry to match market requirements.

Quality Standards and Regulations

Quality standards for reputable micro silica manufacturers are very strict. These include:

• International Standards: Meets ASTM C1240 and EN 13263 requirements


• Environmental Regulations: Following local and international environmental guidelines


• Quality Control: Maintaining consistent product specifications


• Safety Standards: Ensuring safe handling and storage procedures

Impact on Construction Quality

The quality of micro silica greatly determines the outcome of construction. Good producers ensure that their product aids in achieving:

• Greater Concrete Strength: Improved compressive and flexural strength


• Greater Durability: Increased resistance to chemical attack


• Better Workability: Making it easier to place and finish the concrete


• Reduced Permeability: More waterproof structures
