Steel slag, the main solid waste in the steel-making process, is produced more than 120
million tons annually in China. Most of the steel slag was stored in the open air, which …

With the rapid development of economy and industrialization, the consumption of natural
resources has risen sharply. A large number of greenhouse gases and industrial solid waste …

The construction industry is a major contributor of CO 2 emissions. Carbonation, involving
the reaction of CO 2 with alkaline reactants, immobilizes CO 2 into thermodynamically stable …

CO 2 mineralization of cement materials utilizes reaction of calcium or magnesium with
carbonate ions forming insoluble carbonates. Recent research has demonstrated that this …

To solve heavy metals leaching problem in the utilization of various industrial solid wastes,
this work investigated the heavy metals immobilization of ternary geopolymer prepared by …

Given the widespread use of concrete as the construction material of choice, achieving
sustainable development goals in the civil infrastructure sector directly relies on reducing the …

Diffusion of CO 2 strongly influenced the carbonation efficiency of steel slag. A novel
approach for preparing steel slag-based artificial lightweight aggregates (SALAs) was …

Cement-based materials have favorable capacity of solid waste and CO 2 disposal. In this
study, a synergistic CO 2 treatment, including CO 2 mineralization of steel slag admixture …

With increasing interest in utilizing metallurgical slags for mineral carbonation, there is a
need to find applications for carbonated slags. The scope of this study is to explore the …

The low reactivity and volume expansion issue of steel slag limits its application as
alternative to cement. Studies demonstrated that aqueous carbonation (AC) can enhance …
