Mixing method for improving carbon sequestration effect of cement-based material
The invention relates to the technical field of cement-based building materials, in particular to a mixing method for improving the carbon sequestration effect of a cement-based material. According to the method, the cement-based product production alkaline wastewater is adopted as the mixing water, the slurry is firstly pre-hydrated in the stirring process, and then carbon fixation is cyclically carried out according to the processes of gas stirring carbon fixation, gas stopping and standing, gas stirring carbon fixation and gas stopping and standing, so that efficient carbon fixation in the cement-based material mixing process at normal temperature and normal pressure can be realized; a certain amount of organic amine is added to serve as a CO2 absorption promoter, and the CO2 absorption effect can be improved in an auxiliary mode.
本发明涉及水泥基建筑材料技术领域，尤其是涉及一种提高水泥基材料固碳效果的拌合方法。本发明通过采用水泥基制品生产碱性废水作为拌合水，并在搅拌过程中首先对浆体进行预水化，再依照通气搅拌固碳‑停气静停‑通气搅拌固碳‑停气静停工艺循环固碳，可实现常温常压下水泥基材料拌合过程中的高效固碳，并且，添加一定量有机胺作为CO2促吸收剂，可辅助提高CO2吸收效果。
