Silica Fumes For Concrete | Image Resource : image.slidesharecdn.com
 

When silicon or ferrosilicon alloys are produced, silica fumes are produced as a byproduct. This byproduct is used in concrete. The chemical and physical properties of the fumes have made it very reactive. The strength of concrete having silica fumes is very high. This strength increases the life of concrete.
 
People who use concrete for construction can purchase silica fumes from the suppliers. The workers have to pay special attention when using silica fumes with concrete.
 

Electric furnaces are used to produce Silica Fumes for Concrete and the raw materials used are coal, wood chips, and quartz. The production of silicon produces smoke, which is known as silica fume and is sold to the manufacturers. The main ingredient of silica fume that is used for concrete is silicon dioxide, which is in amorphous form.
 
The particles of silicon dioxide are very small. The fume is very reactive because its surface area is large, its content of silicon dioxide is high, and particles are very small.
 

Concrete is one of the cheapest materials used in construction. Previously 6,000 psi concrete was considered as hardest but now due to concrete through silica fumes, the strength has been raised to 15,000 psi.

Concrete starts corroding due to marine salts In this case, silica fumes are a boon as they do not allow the chloride ions to penetrate the concrete. That is the reason that concrete with silica fumes is being used for making residential builds, bridges, and also improving the existing houses and bridges. There are many suppliers who supply the silica fumes for concrete.
 
Mixing of concrete with fumes should be done carefully so that the strength of concrete can be increased. Fumes are available in wet and dry forms and it should be mixed while concrete is being produced.
