A large number of experiments have shown that the steel slag powder can make the concrete as a whole "micro-expansion", which in turn leads to low hydration heat, low slump, high impermeability, high strength, high frost resistance, high wear resistance and high A series of extremely valuable properties such as seawater corrosion resistance, high carbonation resistance and a life span of more than 100 years.
The use of steel slag grinding as a blending material of concrete and cement has high comprehensive benefits, which is an effective way to speed up the environmental protection of steel mills and promote large-scale utilization of steel slag, and has good environmental benefits.

So what is the economic benefit of steel slag powder?
At present, the processing cost of steel slag grinding in China varies from 60 to 100 RMB, which is lower than the price of slag powder and cement. Using 1 ton of steel slag to grind fine powder, it replaced 1 ton of cement, and the price difference is very impressive.
For example, a steel mill sells 20,000 tons of steel slag grinding powder every month, mainly to cement plants and mixing stations. The price per ton rises from 115 RMB in September to 175 RMB in December, and it is in short supply.
It can be seen that the grinding of steel slag has good economic benefits and the development prospect is very broad.
