Silica Fumes For Concrete | Image Resource : image.slidesharecdn.com Silica fumes refer to the derivatives that one gets after producing ferrosilicon alloys or silicon metals. It has quite exceptional physical and chemical properties, making it a highly reactive pozzolan. Silica fumes for concrete give structures a high amount of strength and durability. You can easily buy them from the sellers of concrete admixtures.
Alloys and silicon metal are produced in electrical furnaces and the raw materials which are used in deriving them are wood chips, coal and quartz. The smoke which is collected from operating the furnace is actually collected and sold in the market as silica fumes. Silica fumes are mostly important because they are a great admixture for concrete. Uses Of Silica Fumes for Concrete The silica fumes which are used as an additive in concrete actually consist of non-crystalline or amorphous silicon dioxide. All of the particles are acutely miniature in size, which means that it is 1/100th size of a lone cement particle. Since it is very fine in quality, it forms quite a reactive pozzolan. Using of silica fumes for concrete give the structures and the buildings strength and durability for a long period of time. We see that a lot of the degradation that happens in most of the buildings these days is caused due to the marine salts. Since silica fumes have very little amount of water, it is quite resistant to chloride ions. You can easily buy silica fumes in wet or dry forms from the market. It is used as an additive during the production of concrete at a cement plant. The success rate of producing silica fumes both in the dry batch plants and central mix is always high. The use of silica during the construction of buildings have considerably made all of them stronger.
