Document Type and Number:
WIPO Patent Application WO/2023/087416
Kind Code:
A1
Abstract:
A method for producing a steel slag brick. An activator A and an activator B are used in a production process, and the strength of a steel slag carbonated product can be regulated and controlled by adjusting the ratio and doping amounts of the activators A and B. The activators can significantly improve the degree of carbonation of steel slag and the strength of a carbonated steel slag brick; when 0.4% of Na2SiO3 and 1% of NaHCO3 are doped, compared with a sample having no admixture added, the carbonation weight increase rate of the steel slag brick is increased by 18.6%, and the strength is improved by 59.7%. The method for producing a steel slag brick has the characteristics of being easy to obtain raw materials, low in price, environmentally friendly and the like; in addition, a large amount of carbon dioxide can be fixed, and the resource utilization of solid waste steel slag is improved.
