we are trying to reuse by products of Esfahan steel making company(zob ahan) such as steelmaking slag ,blast furnace slag and convertor sludgein production of bricks,brick pavers,concrete blocks,kerbs and pavers and ceramic pigments.
The quality of fired bricks depends largely upon the soil properties, skill of the moulders and the firemen, no matter which technology is used for firing the bricks. The basic constituents of soil are the clay and silica minerals which contain minerals like alumina, potassium, iron, calcium, sodium, etc. These mineral constituents have various characteristics on brick forming, drying and firing. Good brick quality cannot be achieved from all types of soil. The only way to determine the fired brick quality from a particular soil is to make the desired product on a trial basis and analyze the results. Confirmatory chemical and physical tests of soil are also performed to explain and understand the resulting product quality.
