Silica Fume

Silica fume is a by-product from the silicon, ferrow-silicon producing process from quartz and carbon in electric furnace. It is such as extremely fine spherical particles. Before 1990 it turned out viewed as factory waste. But also in 1987, silica fume concrete was useful for Deepak Fertilisers. It was learned that it has beneficiary effect about concrete, including increase in strength and durability. Now nearly all major projects are applying High Performance Silica Fume concrete. Some of the important projects where silica fume can be used are Tehri Dam, Bandra Worli Seashore Link, Nuclear Power Station, Kaiga, Karwar, Mumbai to Poona express way. Replacing cement by 12. 5 per cent silica fume contains the maximum advantage in increasing the strength. As a result regarding increase in its demand, right now silica fume is expensive. However when analysed against the price tag on an alternative concrete of similar performance it's found to be economical in addition. This conclusion has been drawn on the cost analysis of Mumbai-Poona convey way.
