二氧化碳矿化养护混凝土固碳性能的讨论

Discussion on Carbon Sequestration Properties of CO_(2)Mineral Carbonation Curing Concrete

混凝土具有吸收CO_(2)的能力,利用CO_(2)养护混凝土发生矿化反应生成碳酸盐沉淀和无定形硅胶将CO_(2)永久封存在混凝土中是消纳CO_(2)的一个有效途径。为探索CO_(2)矿化养护混凝土的固碳性能,本文总结了CO_(2)矿化养护混凝土的反应机理,讨论了混凝土固碳性能的评估方法以及检测技术,并对CO_(2)矿化养护混凝土的未来发展进行了展望。

Concrete has the ability to absorb CO_(2).The use of CO_(2)curing concrete mineral reaction generates carbonate precipitation and amorphous silica gel to permanently store CO_(2)in concrete,which is an effective way to absorb CO_(2).In order to explore the carbon sequestrationf performance of CO_(2)mineral carbonation curing concrete.This paper summarizes the reaction mechanism of CO_(2)mineral carbonation curing concrete.The evaluation methods and testing techniques of carbon sequestration performance of concrete are discussed.The future development of CO_(2)mineral carbonation curing concrete is prospected.
