Background
The steel slag is solid waste generated in large quantity by extracting impurities with lime in the steel-making industry, is grey brown, has micropores, is dense and has heavier texture, and the main sources of the steel slag are as follows: oxides and sulfides are generated after elements in the metal furnace burden are oxidized; etched furnace lining and lining materials; impurities brought in by the metal furnace charge and slag-forming materials, such as limestone, iron ore, fluorite and the like, which are purposely added for adjusting the properties of the steel slag. The main chemical components comprise CaO, SiO2, Fe2O3, Al2O3, MgO and the like. The steel slag contains hydration active components (such as calcium oxide and silicon oxide), but in the steel-making process, the active components form dicalcium silicate-based minerals at high temperature to become slow hydration active substances, so that the activity excitation is needed. On the other hand, the steel slag contains MgO and fCaO and also has a micro-expansion characteristic, and the steel slag powder is directly used in concrete engineering and can cause the expansion and cracking of the concrete, thereby influencing the popularization and application of the steel slag powder in the concrete engineering. The invention mainly aims to reasonably utilize a large amount of waste steel slag, reduce the quality while ensuring the strength to be unchanged, save materials, resist heat and sound, and produce a large batch of high-quality building materials.
