Research on the mortar properties of basic oxygen furnace slag based on component adjustment by electric arc furnace slag
The use of steel slag to prepare cementitious materials has significant economic and environmental benefits. However, steel slag has shortcomings such as large fluctuation in composition, high content of free calcium oxide, and difficulty in stable control of product quality in industrial production, which seriously restricts the large-scale applications of steel slag in building materials industry. This study proposes to use electric arc furnace (EAF) slag as a component adjustment material to react with basic oxygen furnace (BOF) slag at high temperature, in order to optimize the composition and structure of BOF slag, thereby improving its cementitious activity. The results show that using EAF slag as a component adjustment material to remelt BOF slag at high temperature can improve the cementitious properties of BOF slag mortar samples at various curing ages. When the early cementitious properties are the main target, the optimal remelting conditions are: the remelting temperature is 1150 °C–1200 °C, and the dosage of EAF slag is 10%–15%.
