Ferro Silicon Slag Silicon slag is byproducts during the product of ferrosilicon, ferrosilicon slag is used to recycle pig iron and common casting in steel slag and so on, it can improve furnace temperature significantly,increase the liquidity and discharge iron slag effectively, increase the label.
Recycling slag minimizes waste and disposal costs, reduces energy use, extends furnace life, and lowers the amount of additives needed to make slag. The concerns with slag recycling are that first, because slag can contain environmentally hazardous materials, it must be analyzed for elemental composition before reuse.
Today, iron and steel slag is used in many fields where its unique characteristics can be put to effective use. As a result of growing environmental awareness, iron and steel slag is highly regarded as a recycled material that can reduce impacts on the environment due to its resourceconservation and energysaving effects.

In the row, this study sought to replace the industrial and construction waste by fine and course aggregate respectively. With this concern, this study considered the replacement cementitious material as copper slag, iron slag for fine aggregate and recycled concrete aggregates for coarse aggregate.
Slag from steel mills in ferrous smelting, on the other hand, is designed to minimize iron loss and so mainly contains oxides of calcium, silicon, magnesium, and aluminium. Any sandy component or quartz component of the original ore automatically carries through the smelting process as silicon dioxide.
