In recent years, with the continuous expansion of environmental protection, China has made clear regulations and requirements for the utilization of industrial waste slag. As a result, more and more companies are gradually paying attention to slag, water slag, steel slag, fly ash, etc industrial waste residue follow-up problem.

As a by-product of blast furnace ironmaking, people have gained a deeper understanding of blast furnace slag in recent years. In terms of application, blast furnace slag has the following advantages:

 1.Improve the workability of concrete

The slag powder needs a small amount of water, and after mixing, the water-cement ratio of the concrete can be reduced, and the amount of concrete bleeding can be reduced, thereby increasing its fluidity, workability, and pumpability so as to maintain its good workability.


 2.Reduce the heat of hydration of concrete

Because part of the cement can be replaced by equal amounts, the exotherm during the hydration of the cement is reduced, thereby reducing the temperature rise of the concrete and avoiding the cracking of the concrete caused by the excessive temperature rise of the concrete.

 3.Improve the strength of concrete

Without changing the water-cement ratio, using some of the ore powder instead of cement to mix in the concrete will increase the strength of the concrete due to the effect of temperature rise.

 4.Improve the durability of concrete

The incorporation of mineral powder reduces the corrosivity of the cement, and the finer particles of ore are evenly distributed in the cement, which can inhibit the alkali aggregate reaction of the concrete, improve the resistance to sulphate, and increase the resistance to seawater corrosion.

As one of the professional powder processing industries, Guilin Hengda Mining Machinery Co., Ltd with its advanced technology and innovative development advantages, proposes an overall solution for the preparation of slag powder, which not only meets the development trend of energy saving and environmental protection in the international cement industry, but also enables various types of industrial solids. The secondary recycling of waste is an inevitable choice for cement/commercial mixed-station enterprises with high-cost slag powder production equipment.
