This study proposes a semi-wet CO<sub>2</sub> mineralization method to modify wollastonite (WS) and successfully synthesizes a reactive cementitious material—carbonated wollastonite (CWS)—that is rich in carbonate and amorphous SiO<sub>2</sub>. This innovative method not only imparts significant pozzolanic activity to the CWS but also enables efficient CO<sub>2</sub> sequestration. This study systematically outlines the CWS preparation process and investigates its influence on the hydration characteristics, microstructural evolution, and performance development of a high-early strength cement (HEC) system. Additionally, a comparative analysis with slag and fly ash is conducted. The results of this study revealed that CWS exhibited a slight hydration inhibition effect in the early stage, which gradually diminished over time. After 28 days, the strength of the CWS system surpassed that of pure HEC, and its resistivity increased by 79.3 %, significantly exceeding the 24.1 % improvement observed in the slag system. CWS not only exhibits pozzolanic activity but also interacts synergistically with the aluminum phase. Its ability to consume calcium hydroxide and generate hydration products surpasses that of slag and fly ash, effectively reducing the total pore volume to a level comparable to that of the pure HEC system. In addition, the unique preparation process of CWS shows an excellent CO<sub>2</sub> sequestration potential of 285.5 g CO<sub>2</sub>/kg. This method not only offers an effective solution to mitigate the current shortage of SCMs but also provides a sustainable approach for the construction industry, combining high performance with low carbon emissions.</div></div>","PeriodicalId":9865,"journal":{"name":"Cement & concrete composites","volume":"164 ","pages":"Article 106254"},"PeriodicalIF":10.8,"publicationDate":"2025-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144701763","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

High-strength engineered cementitious composite (HS-ECC), combining the excellent tensile behavior of ECC (especially the tensile strain capacity) and the compressive performance of UHPC, could work compatibly with steel bars for the whole loading process preventing crack localization. This enhances both load and deformation capacity of HS-ECC structure.

The requirement of HS-ECC tensile strain capacity decreased, while the requirement of HS-ECC compressive strain capacity increased with increasing reinforcement ratio.
