10 important functions of silica fume in concrete

Silica fume can fill the pores between cement particles, and at the same time form a gel with the hydration product, and react with the alkaline material magnesium oxide to form a gel. Adding an appropriate amount of silica fume to cement-based concrete, mortar and refractory castables can play the following roles:

The difference between white silica fume and gray silica fume

White silica fume and gray silica fume are two kinds of silica fume materials with different colors, and their main difference lies in the color. In addition, there are some differences in application and properties, which are detailed below:

The difference between metal manganese and electrolytic manganese

The metal manganese obtained by electrolysis after treating manganese powder with chemical raw materials such as sulfuric acid is called "electrolytic manganese", which is a chemical process. Manganese carbonate and other manganese compounds in manganese ore become metal manganese.

Ferrosilicon alloys and silicon metal have different uses

In summary, ferrosilicon alloys are mainly used in the steel industry, while silicon metal is used in the production of electronics, solar energy, and alloys.

Manufacturing process of ferrosilicon

Silicon iron is an alloy made from silicon and iron, which is widely used in the steel industry for its properties such as high silicon content, good resistance to oxidation and corrosion, and high temperature stability. The manufacturing process of silicon iron involves several steps, as outlined below:

Difference between ferromanganese and silicomanganese

Ferromanganese and silicon manganese are both added raw materials in steelmaking, mainly used to remove oxygen from steel and increase the toughness and strength of steel. They are indispensable substances in steelmaking.

What is the difference between silicon ferroalloy 、silicon barium inoculant and silicon barium calcium inoculant

Metallurgical silicon ferroalloy, silicon barium inoculant, and silicon barium calcium inoculant are all commonly used inoculants in the metallurgical industry. However, there are some differences between them:

What is the difference between silicon slag and ferrosilicon slag

Silicon slag generally refers to the remaining part of the raw ore after refining, and also contains a certain amount of silicon. There are many types of silicon slag, including industrial silicon slag, solar silicon slag, semiconductor silicon slag, and so on.

Are emery and silicon carbide the same abrasive?

Regarding corundum and silicon carbide, the connection between the two is really unclear. Some people think that the two are the same thing, and some think it is not. But looking up information on the Internet, the two seem to be different. It is indeed the same thing, so are emery and silicon carbide the same thing?

Can silicon carbon alloy replace ferrosilicon?

As an alloy variety for converters, silicon carbon alloys can replace ferrosilicon, silicon carbide, and recarburizers, reduce the amount of deoxidizers, and be used in deoxidation alloying processes for converter smelting. The effect is stable, and the chemical composition, mechanical properties and internal control quality of steel types are superior to traditional techniques.
