Loess-based composite coal gangue porous vegetation concrete and preparation method thereof
The invention discloses loess-based composite coal gangue porous vegetation concrete and a preparation method thereof. The loess-based composite coal gangue porous vegetation concrete comprises the following raw materials in parts by weight: 3600 parts of coal gangue; 473.6 parts to 840.8 parts of loess, 473.6 parts 51.8 parts to 141.2 parts of cement; 14.1 to 28.2 parts of slag powder; 7.1 to 21.2 parts of fly ash; and 232.3 to 381.2 parts of water. And 0.71 to 3.39 parts of a water reducing agent. The loess is used for replacing most of cement to serve as a cementing material to prepare the vegetation porous concrete, the use amount of the cement can be reduced, high-carbon emission caused by cement preparation is reduced, the loess is obtained locally, and the cost can be reduced to a great extent. The solid waste coal gangue is used for replacing pebbles, so that the stacking of wastes can be reduced, the demand on natural pebbles is reduced, and the influence on the natural environment is reduced. Good ecological benefits and social benefits are achieved, and the application prospect is wide.
本发明公开了一种黄土基复合煤矸石多孔植生混凝土及其制备方法，包括以下重量份数原料：煤矸石3600份；黄土473.6份‑840.8份；水泥51.8份‑141.2份；矿渣粉14.1份‑28.2份；粉煤灰7.1份‑21.2份；水232.3份‑381.2份；减水剂0.71份‑3.39份。本发明以黄土代替绝大多数水泥作为胶凝材料来制备植生多孔混凝土，可降低水泥的用量，减少因水泥制备造成的高碳排放，黄土就地取材，可在很大程度上降低成本。以固体废弃物煤矸石代替石子，可减少废弃物的堆放，减少对天然石子的需求，降低对自然环境的影响。具有良好的生态效益和社会效益，应用前景较为广阔。
