Besides tailings, the solid waste discharged from iron and steel enterprises is mostly smelting slag, mainly including blast furnace slag, slag, steel slag, iron alloy slag, etc. The smelting slag storage not only occupies a large amount of land, but also causes certain environmental pollution, and causes harm to the health of the public. Therefore, the comprehensive utilization of steel slag to achieve its reduction, reuse and harmlessness is very necessary for the sustainable development of the steel industry.

GGBFS is a kind of concrete admixture with superior performance. Adding GGBS during cement production can increase the strength 28D of cement by 15% - 20%, to admix 42.5 grade cement, and during concrete production, slag powder can replace 10 ~ 50% of the cement, to mix C20 ~ C60 concrete, which has become an important measure to reduce the cost of cement in the international cement industry.

CHAENG can undertake EPC turnkey services for GGBS (Ground granulated blast-furnace slag plant) plant with an annual output of 200,000-1,500,000 tons. So far, CHAENG has established successfully more than 100 GGBS plant in the world.
