Composite cementing material as well as preparation method and application thereof
The invention relates to a composite cementitious material and a preparation method and application thereof, and the composite cementitious material comprises cement and activated carbon prepared by performing pyrolysis treatment on coffee grounds. The composite cementing material comprises the following components in percentage by mass: 40-60% of activated carbon. According to the invention, cement is partially replaced by activated carbon prepared by pyrolysis treatment of coffee grounds, and the obtained composite gelling material has good adsorption performance on heavy metal ions, can be arranged on the surface of a road or a building, and well adsorbs heavy metal ions leaked and accumulated on the surface of the road or the building. The composite cementing material disclosed by the invention can realize the effect of stably adsorbing and removing heavy metal ions for a long time through the synergistic effect of multiple adsorption mechanisms.
本发明涉及一种复合胶凝材料、其制备方法与应用，复合胶凝材料，包括水泥以及由咖啡渣经过热解处理制备得到的活性炭。按照质量分数计，复合胶凝材料中包括40‑60％的活性炭。本发明以由咖啡渣经过热解处理制备得到的活性炭部分替代水泥，得到的复合胶凝材对重金属离子具有较好的吸附性能，能够设置在道路或者建筑物表面，对道路或者建筑物表面外渗以及积累重金属离子进行良好的吸附。本发明的复合胶凝材料可以通过多种吸附机理协同作用，以实现长期稳定地吸附和去除重金属离子的效果。
