摘要
二氧化碳与新拌混凝土或再生混凝土骨料等水泥基材料反应会生成热稳定性的碳酸钙,该方法不但能使新拌混凝土快速获得强度以及提高再生混凝土骨料的强度,还能封存二氧化碳.综述分析了国内外相关文献对水泥基材料封存二氧化碳的理论方法、试验方法和经验模型等的研究进展,以期为准确度量水泥基材料封存二氧化碳提供较为全面的参考依据.
Calcium carbonate,which is a thermostable substance,is formed based on reactions between carbon dioxide and fresh concrete and recycled concrete aggregates. This method can not only make fresh concrete obtain strength quickly and improve the strength of recycled concrete aggregate,but also sequester carbon dioxide. In this paper,the theoretical methods,experimental methods and empirical models used by scholars to evaluate the sequestration of carbon dioxide in cement-based materials are reviewed in order to provide a systematic basis for accurate measurement of carbon dioxide sequestration of cement-based materials.
