A mini review of mineral carbonation of solid materials

Abstract

Mineral carbonation of solid materials  (MC-SM) has garnered significant attention for its potential to reduce carbon dioxide emissions. This study presents a thorough overview of research trends and hotspots in MC-SM through bibliometric analysis. Articles were sourced from the Google Scholar core database, covering the period from 2000 to 2020, and were analysed in detail. The findings indicate that MC-SM is an emerging research area, with rapidly changing key topics. China and Switzerland lead in publication numbers and average citations, respectively. Carbonation curing typically enhances the strength and durability of materials due to carbonate formation. In terms of carbon dioxide storage capacity, materials such as carbide slag, reactive magnesium oxide cement, and β-C2S are effective, while fly ash, mine tailings, and carbon mixes show limited activity. The slow kinetics and low carbonation rates currently hinder the large-scale industrial application of MC-SM.
