The blast furnace slag is an industrial waste produced in the production of steel. The coal-fired units of the power plant will produce ash after coal combustion during the power generation process, that is, fly ash and slag. The main use of the finished product is mineral admixtures for concrete.

Northwest 60 million tons of slag powder preparation project, the use of LM slag mill. Processing materials and fineness : blast furnace slag ( water slag ) ≥ 400 m2 / kg

Slag powder is a kind of waste slag discharged from blast furnace when smelting pig iron. It can be used as concrete admixture after grinding treatment. Slag, also known as granulated blast furnace slag, is a by-product of blast furnace ironmaking and has high potential activity and hydraulicity.

Main uses :
1, cement production in a certain proportion directly into the cement, is a component of the production of slag Portland cement material, in order to improve the performance of cement and reduce production costs and energy consumption, slag Portland cement in the water slag by weight of 20 % -70 %.
2.In ready-mixed concrete and cement products, equal or excessive replacement of some cement is used as cementitious material to directly mix concrete and mortar to improve its working performance. Slag powder appears in the construction market as a vertical product and is widely used in concrete. It can replace about 50 % cement.
