Silica fume Properties

Silica fume, also known as microsilica (CAS number 69012-64-2, EINECS number 273-761-1). It is divided into two types: densified microsilica and undensified microsilica . Microsilica is a fine powder with particle size less than 1 micron and has a high silicon dioxide (SiO2) content of about 85% – 99%.

Silica Fume Applications

Silica fume is added to concrete as a supplementary cementitious material (SCM) to improve its durability, strength, and workability. It reacts with the calcium hydroxide produced during the hydration of cement to form additional C-S-H gel, which is the primary binding material in concrete.

In addition to its use in concrete, silica fume is also used in other applications, such as refractories, mortars, grouts, and as a filler in various polymer composites. The high reactivity of silica fume also makes it useful in the production of high-performance ceramics, refractory linings, and fireproof materials.

Precautions for buying silica fume wholesale

When buying silica fume wholesale, it’s important to consider the properties of the product and ensure that it meets the specifications required for your application. For example, if you’re using silica fume in concrete, you’ll want to make sure that it has a high SiO2 content and a consistent particle size. Some suppliers may offer different grades of silica fume, so it’s important to choose the right grade for your specific application.

Wholesale silica fume is usually sold in bulk, either in bags or in bulk containers. The price of silica fume varies depending on the quantity purchased and the delivery location. Some factors that can affect the cost of silica fume include transportation costs, demand, and production costs.

When purchasing silica fume wholesale, it’s also important to consider the quality of the product and the reputation of the supplier. High-quality silica fume should have consistent particle size and a low moisture content. Some suppliers may offer discounts for large orders, but it’s important to balance the cost savings with the quality of the product.
