Ferrosilicon is a mixture of iron and silicon that is produced in an electric arc furnace in various grades, including 10 to 90 percent; which refers to the amount of silicon present in the mixture, but the grades required by the industry, especially the steelmaking industry, are 70 to 75 percent.
Microsilica is a highly reactive material that is used in small amounts to enhance the properties of concrete. This material is a by-product of electric arc furnaces used to produce special alloys (ferro-silica). The following page explains the types of microsilica and their uses, as well as the method and amount of consumption.
