Abstract: A method for thermal activation of coal gangue and in-situ carbon fixation utilizing waste heat from steel slag is disclosed. By utilizing waste heat from high-temperature molten steel slag, coal gangue is activated to a high pozzolanic activity utilizing the system temperature of a steel slag hot-steaming device, and meanwhile, the CO2 released in the thermal activation process is captured utilizing the reaction of steel slag with CO2 to generate stable carbonates, thus achieving permanent carbon sequestration. The present disclosure effectively uses the heat from the hot steel slag discharged from the steelmaking furnace in such a way that the coal gangue is activated while the steel slag undergoes a carbonation reaction, resulting in an increased heat recovery rate during the cooling process of the steel slag.
