Silicon is an element, chemical in nature mostly used in making electronic circuits. It is semi-conductive in nature and is shiny dark grey in colour. It exists as an amorphous (non-crystalline) powder. While manufacturing the non-metal silicon or a ferrosilicon alloy, a lot of by-products are produced. One such by-product is silica fume. One of the most important use of silica fume is in concrete. It is a highly reactive pozzolan because of its physical and chemical properties. Silica fume for concrete has a very high strength and high durability.
What does it consist of?
Silica fume mainly consists of non-crystalline (amorphous) silicon dioxide, the chemical notation for which is Sio2. A singular silicon particle is very small, about 1/100th of the average cement particle. It is a highly reactive pozzolan due to its extremely fine particles, huge surface area and high concentration of silicon dioxide. Therefore, silica fume for concrete is desirable.
Where and how?
One can use silica fume in concrete in both wet or dry forms, as both are available. The fume is added to the concrete during production at a concrete plant. It is successfully produced in both central-mix and dry-batch plants. Assistance is always nearby when handling silica fume in concrete. It is used to produce high-quality and consistent concrete.
It was only a few years ago that 6,000 PSI concrete was stopped from being considered high strength. Thanks to the addition of silica fume in concrete, today it is possible to produce concrete with compressive strength of more than 15,000 PSI.
