Method for preparing high-quality recycled aggregate from novel carbon sequestration functional powder material
The invention discloses a method for preparing high-quality recycled aggregate from a novel carbon sequestration functional powder material, and relates to the field of low-carbon concrete. The method for preparing the high-quality recycled aggregate from the novel carbon sequestration functional powder material comprises the following steps: pretreating concrete, mixing, mixing and stirring, carrying out carbon sequestration pre-wetting, and air-drying. According to the method for preparing the high-quality recycled aggregate from the novel carbon sequestration functional powder material, a metal organic framework compound is introduced as a carbon dioxide adsorption carrier, carbon dioxide is transported into gaps of the recycled aggregate, and gradual carbonization is performed from the inside to the outside of the gaps of the recycled aggregate; the carbon dioxide is gradually carbonized from the mortar on the surface of the recycled aggregate to the inside, so that the carbonization efficiency of the recycled aggregate is effectively improved.
本发明公开一种新型固碳功能性粉体材料制备高品质再生骨料的方法，涉及低碳混凝土领域。该新型固碳功能性粉体材料制备高品质再生骨料的方法，混凝土的预处理、混合处理、混合搅拌处理、固碳预湿处理和风干处理。该新型固碳功能性粉体材料制备高品质再生骨料的方法，通过引入金属有机骨架化合物为二氧化碳吸附载体，将二氧化碳运输至再生骨料空隙中，从再生骨料空隙内部向外部进行逐步碳化，与二氧化碳从再生骨料表面砂浆逐渐向内部进行碳化相结合，有效的提高了再生骨料的碳化效率。
