为了更好地利用透水混凝土的多孔特性，提出并设计了一种新型的流通法养护装置，旨在探索更适合透水混凝土的CO2养护方法.通过试验探讨了养护时间这一关键参数，并且在固碳率、抗压强度和微观结构等方面与传统的静态养护方法（包括加压和常压养护）进行了对比.结果表明：流通法能够通过气流带走透水混凝土内部多余的水分，从而实现水分的均匀分布，同时还能减少预处理步骤并促进混凝土的碳酸化；流通法有效消除了试件内外的碳化不均匀，显著提升了混凝土的抗压强度.
In order to better utilize the porous characteristics of pervious concrete and find a more suitable CO2 curing method for it， a novel flow method for curing pervious concrete was proposed and a corresponding curing apparatus was designed. Experimental approaches were used to explore the curing time of the flow method， and a comparison was made with commonly used static curing methods including pressure curing， which shows superior performance， and atmospheric curing under similar conditions， with respect to CO2 uptake， compressive strength， and microstructure. The results show that the flow method can promote carbonation by removing excess moisture， especially from the interior of the concrete， through airflow， reducing the need for pre-treatment steps and ensuring a more uniform distribution of moisture. This effectively eliminates the uneven carbonation inside and outside of the specimens， with the result that it significantly improves the compressive strength of the concrete.
