What is silica fume? Definition The American concrete institute (ACI) defines silica fume as a “very fine non-crystalline silica produced in electric arc furnaces as a by-product of the production of elemental silicon or alloys containing silicon.” It is usually a grey colored powder, somewhat similar to Portland cement or some ﬂy ashes. It can [...]

How microsilica works in concrete? Microsilica is a product of silicon metal smelting. Most particles are less than 1 micron in diameter (0.00004 inches), It's usually 100 times thinner than normal cement, It is produced in an arc furnace of 2000 degrees Celsius and released from the liquid at the bottom of the furnace. As the steam rises, it is produced through a complex process [...]

In fact, they belong to a substance but differ in the name. the difference between silica fume powder and microsilica, Silica fume is more focused on silica in the form of dust because its bulk density is relatively small, about 200-320 Kg/m3, and is usually used to indicate that there is no encrypted silica fume. Micro-silica powder is more [...]

How to densify silica fume Why do we need densified silica fume? Because densified silica fume can bring us the following benefits. First, the volume of silica fume reduced under the same mass. The transportation efficiency is improved and the transportation cost is saved. Second, the encrypted silica fume is a granular ball, making it difficult to adsorb on the [...]

What is Microsilica? Microsilica is a byproduct of producing silicon metal or ferrosilicon alloys. One of the most beneficial uses for Microsilica is concrete. Because of its chemical and physical properties, it is a very reactive pozzolan. Concrete containing Microsilica can have very high strength and can be very durable. Placing, finishing, and curing silica-fume concrete require special attention on the part [...]

how to use silica fume in concrete? As early as 1940, silica fume was discovered and collected and used. Today, silica fume is widely used in concrete engineering Because silica fume concrete is stronger and more durable than traditional concrete，and has reached more than 14,000 psi. In addition, the corrosion of steel is reduced as the reaction product of very [...]
