摘要
Abstract
The experiment involves carbonizing steel slag with gases of different CO2 concentrations(20%,30%,40%and 99.9%)to detect the weight gain rate and free calcium oxide(f-CaO)content of the steel slag after the carbonation reaction,at the same time,thermal gravimetric analysis and microstructure analysis are performed on the steel slag after the carbonation reaction.Research has shown that when the CO2 concentration is less than 30%,the effect of CO2 concentration changes on the carbonation efficiency of steel slag is not significant.When the CO2 concentration is greater than 30%,the change in CO2 concentration has a significant impact on the carbonation effect of steel slag,as the CO2 concentration increases,the carbonation effect of steel slag improves.关键词
