Ground granulate blast furnace slag

Product Description

Ground Granulated Blast Furnace slag powder is a by-product from iron production in blast furnaces. The blast furnace naturally separates from the iron, then collected and cooled with large amount of cold water. This quenching process leads to transformation of liquid into small sized particles having amorphous particles structure. The major use of Ground Granulated Blast furnace slag powder applies to ready-mixed concrete. During the production of ready-mixed concrete, Ground granulated blast furnace slag powder replaces about *0% of normal Portland cement content, generally about *0%, but sometimes up to *0%.The higher the proportion, the better is the durability. The disadvantage of the higher replacement level is that early-age strength development is somewhat slower. Ground granulated blast furnace slag powder is also used in other forms of concrete, including site-batched and precast.
