摘要: 本文从水泥材料碳汇发生原理、碳化影响因素、混凝土水泥碳汇、砂浆水泥碳汇与水泥窑灰碳汇等方面,综述水泥材料整个生命周期碳汇的相关研究。众多研究表明,水泥材料的碳化过程受水泥的材料因素和环境因素影响较大;混凝土在建筑使用阶段的碳汇量核算方法主要通过碳化深度定量表达,而在拆毁和回收利用阶段的碳汇核算方法缺乏;砂浆水泥和水泥窑灰的碳化速度要高于混凝土,但其碳汇核算方法仍未建立。今后的研究应侧重以下几个方面:继续加强水泥材料碳汇影响因素及相应碳化参数的研究,从生命周期角度系统建立完整的水泥材料碳汇核算方法体系;精确核算中国乃至全球水泥材料年碳吸收量、碳汇累积量,并分析水泥材料碳汇在碳失汇中的贡献比例;从生态学和气候变化视角阐述水泥材料碳汇对城市碳循环的影响。

Abstract: This paper summarized the research progress on the cement carbonation principles, impact factors, concrete carbonation, cement mortar carbonation, and the cement kiln dust carbonation. Numerous studies showed that the carbonation rate coefficients are mainly impacted by material and environmental factors; the concrete cement carbon sequestration in service stage can be quantitatively calculated by the carbonation depth, and the calculation methods of cement carbon sequestration in demolition and crushing stage, and waste treatment and secondary use stage are still lack; the carbonation rate coefficients in mortar cement and cement kiln dust are higher than those in the concrete, but their carbon sequestration calculation methods have not been established. Future researches should focus on: (1) the carbonation rate coefficients of cement materials should be clarified, and the cement carbon sink calculation methodology from life cycle assessment perspective should be built systematically; (2) annual cement materials carbon sequestration and accumulated carbon sequestration in both China and around the world should be calculated, and their contributions to global missing carbon sink should be analyzed; (3) the significance of cement materials carbon sink on urban carbon cycle should be explained from both ecology and climate perspectives.

Key words: carbon sink, cement materials, missing carbon sink, carbon cycle, climate change
