摘要

The construction industry faces significant challenges in reducing carbon emissions due to increasing demands driven by urbanization, population growth, and infrastructure development. Cement, a fundamental material in this sector, is one of the largest contributors to greenhouse gas emissions. Given the industry’s substantial carbon footprint, it is imperative for the construction sector to support global net-zero emission targets, such as those established at COP21. Carbon capture, utilization, and storage (CCUS) has emerged as a promising approach, with Accelerated Carbonation Curing (ACC) identified as particularly suitable for the precast concrete industry. This paper presents a bibliometric analysis to trace the development and research trends of ACC as a CCUS technique. The analysis was conducted using data extracted from Scopus. Key bibliometric indicators such as publication trends over time, citation analysis, co-authorship networks, and keyword co-occurrence were employed to identify influential authors, journals, institutions, and countries contributing to this field. The bibliometric insights are followed by a technical review of carbonation curing, examining its mechanisms, influencing parameters, and its impact on the various properties of cementitious system. Furthermore, the paper evaluates the CO₂ sequestration potential of ACC and suggests sequestration 10–20% of CO₂ by binder weight, equating to approximately 40–80 kg of CO₂ per cubic meter of concrete, making it a highly effective carbon mitigation technique within the construction sector. Along with a comparative analysis of cost and energy consumption against conventional curing methods. ACC demonstrates substantial advantages, consuming approximately 85% and 88% less energy compared to traditional precast and autoclave curing methods, respectively. The study also discusses existing commercial ACC technologies and real-world applications. While several companies have begun implementing ACC in practice, the absence of standardized codes and regulatory frameworks limits its broader adoption.
