Influences of binder composition and carbonation curing condition on the compressive strength of alkali-activated cementitious materials: A review

Abstract

As international endeavors to diminish carbon emissions persistently escalate, the principles of net-zero emissions or carbon neutrality have gained prominence, prompting the implementation of diverse strategies globally to alleviate carbon emissions. Cement manufacturing represents a significant emission source globally, and has established formidable objectives to curtail emissions by over 60% by 2050. This review article scrutinizes the ramifications of the amalgamated composition of cement and alkali-activated construction substances, in addition to carbonation curing conditions, on compressive resilience. Initially, the resistance attributes of multi-component materials premised on alkali-activated binding agents were examined. Subsequently, the primary variables influencing the performance of cementitious materials, encompassing Portland cement, were determined. Lastly, the compressive resilience traits of these substances were assessed under an array of carbonation curing circumstances.
