Method for enhancing solid content of carbon dioxide in cement-based material
A method for enhancing carbon dioxide solid content in a cement-based material mainly comprises the following steps: uniformly mixing a CO2 absorbent with the cement-based material, selecting compression molding or pouring molding according to the state of the mixture, demolding after molding, and carrying out CO2 curing. According to the invention, the CO2 absorbent is added into the cement-based material, so that the mixture of the cement-based material and the CO2 absorbent absorbs CO2 gas before molding or in the curing process, and the part of CO2 gas can be released along with the proceeding of the subsequent curing process, thereby achieving the carbonization process from inside to outside. According to the method, the CO2 solid storage degree of the cement-based material can be improved, the compactness and strength of the material are improved, and compared with methods of greatly increasing CO2 pressure and the like in the curing process, the cost is low, the process is simple, and CO2 can rapidly migrate and react in the cement-based material.
一种增强二氧化碳固存在水泥基材料中的方法，主要包括以下步骤：将CO2吸收剂与水泥基材料均匀混合，根据混合料的状态选择压制成型或者浇筑成型，成型后脱模并进行CO2养护。本发明通过在水泥基材料中加入CO2吸收剂，使水泥基材料与CO2吸收剂的混合料在成型之前或者养护过程中吸收CO2气体，该部分CO2气体能随着后续养护过程的进行而释放，从而达到由内而外的碳化过程。本发明可以提高水泥基材料的CO2固存程度，并且提升材料的密实度与强度，相比于在养护过程中大幅增加CO2压力等方法，成本较低，工艺简单，使得CO2可以在水泥基材料内部进行快速迁移和反应。
