Description

technical field

[0001] The invention belongs to the technical field of building materials, and in particular relates to a production process of steel slag ore powder. Background technique

[0002] Steel slag is a huge amount of metallurgical slag. At present, my country's annual output of steel slag is about 10 million tons. Most of the steel slag has not been effectively utilized. On the one hand, it takes up a lot of scarce land resources to build storage yards, and it is easy to cause secondary damage to the environment. Pollution, on the other hand, is also a waste of resources. Steel slag contains a certain amount of C 2 S, C 3 Cement clinker minerals such as S and some vitreous bodies have considerable hydration activity and have the potential to be used to prepare cementitious materials. However, there are two reasons that severely restrict the popularization and application of steel slag: First, steel slag contains a large amount of metallic iron, which leads to ex...
