Introduction to Silica Fume
Silica fume, also known as microsilica, is a by - product of the silicon and ferrosilicon alloy production in electric arc furnaces. It is a very fine powder consisting primarily of amorphous silicon dioxide. Due to its extremely small particle size (about 100 times smaller than the average cement particle) and high silica content, silica fume has unique pozzolanic properties.
In the construction industry, silica fume is widely used as a supplementary cementitious material. When added to concrete, it can significantly improve the mechanical properties of concrete, such as compressive strength, flexural strength, and abrasion resistance. It also enhances the durability of concrete by reducing permeability, which helps to prevent the ingress of harmful substances like chlorides and sulfates, thus protecting the reinforcement from corrosion. In addition, silica fume is used in refractory materials, high - performance ceramics, and other industrial applications.
Now, let's take a look at the top 10 silica fume factories in China in 2025.
