Driven by the“dual carbon”and“green metallurgy”targets,the steel industry feels the pressure of carbon emission reduction and steel slag resource utilization.Since the year 2000,accelerated carbonation technology ...
Carbonation is a natural aging process that occurs in all types of concrete. One of its primary implications is the acceleration of steel corrosion caused by the phenomena of depassivation. The goal of this research i...
