Preparation method of cement-based material for realizing carbon sequestration and utilization
The invention discloses a preparation method of a cement-based material for realizing carbon sequestration and utilization, which comprises the following steps: drying a porous aggregate carrier compatible with the cement-based material, then placing the porous aggregate carrier in a closed space, and replacing air in the porous aggregate carrier with carbon dioxide; stirring the porous aggregate carrier so that the porous aggregate carrier is fully contacted and adsorbed with carbon dioxide; after adsorption is completed, sealing liquid is sprayed to the porous aggregate carrier, a packaging film is formed on the surface of the porous aggregate carrier, and the packaging film is dissolved in water or in an alkali environment of concrete; the preparation method comprises the following steps: uniformly mixing various components of the concrete, finally feeding and mixing the packaged porous aggregate carrier, and pouring and forming; in the hydration process of the concrete member, the packaging film on the surface of the porous aggregate carrier is dissolved in water or in an alkali environment of concrete, carbon dioxide is released, and the concrete member is cured. The concrete is carbonized from the inside to the outside, the inside of the concrete is in a scattered flowering type carbonization mode, and the cement-based material around the porous carrier is in contact with carbon dioxide at the maximum probability, so that the interface transition area of the porous carrier is strengthened.
本发明公开了一种实现碳封存与利用的水泥基材料的制备方法，包括如下步骤：将与水泥基材料相容的多孔骨料载体烘干，然后将多孔骨料载体置于密闭空间，并将其中的空气替换为二氧化碳；搅拌多孔骨料载体，使其与二氧化碳充分接触吸附；吸附完成后，向多孔骨料载体喷洒封裹液，在多孔骨料载体表面形成封装膜，所述封装膜遇水溶解或遇混凝土的碱环境溶解；将混凝土的各种组分混匀后，最后将封装后的多孔骨料载体进行投料，拌合后，浇筑成型；在混凝土构件水化过程中，多孔骨料载体表面的封装膜遇水溶解或遇混凝土的碱环境溶解，二氧化碳释放，对混凝土构件进行养护。混凝土由内部向外部碳化过程，混凝土内部呈现散点开花式碳化模式，多孔载体周围水泥基材料最大概率接触二氧化碳，因此多孔载体界面过渡区得到强化。
