Carbonized regenerated aerated concrete as well as preparation method and application thereof
The invention relates to the technical field of construction waste recycling and heavy metal pollution control, in particular to carbonized regenerated aerated concrete as well as a preparation method and application thereof, and the preparation method comprises the following steps: crushing and grinding waste aerated concrete to obtain waste aerated concrete regenerated particles; carbonizing the waste aerated concrete regenerated particles to obtain carbonized regenerated aerated concrete; during carbonization, the waste aerated concrete regenerated particles are subjected to a carbonization reaction to form nano calcium carbonate and a three-dimensional porous structure amorphous silica gel carbonization product. The preparation method of the carbonized regenerated aerated concrete not only provides a new way for improving the structural performance of the waste aerated concrete, but also indicates that the carbonized regenerated aerated concrete possibly shows excellent adsorption performance in the aspect of heavy metal removal; in addition, the ecological environment problem of high emission of carbon dioxide greenhouse gas is solved to a certain extent, and the problem of recycling of waste aerated concrete construction waste is solved.
本发明涉及建筑垃圾再利用及重金属污染控制技术领域，尤其是涉及一种碳化再生加气混凝土及其制备方法和应用，包括以下步骤：将废弃加气混凝土进行破碎、研磨，得到废弃加气混凝土再生颗粒；将废弃加气混凝土再生颗粒进行碳化，得到碳化再生加气混凝土；所述碳化时，废弃加气混凝土再生颗粒发生碳化反应形成纳米碳酸钙、三维多孔结构无定型硅胶碳化产物。本发明碳化再生加气混凝土的制备方法不仅为改善废弃加气混凝土的结构性能提供了新途径，而且预示着碳化再生加气混凝土在重金属去除方面可能展现出优异的吸附性能；此外，还在一定程度上解决二氧化碳温室气体排放高的生态环境问题，以及废弃加气混凝土建筑垃圾再利用问题。
