Bone meal filter material, preparation method thereof and self-compacting pervious concrete containing bone meal filter material
The invention provides a bone meal filter material, a preparation method thereof and self-compacting pervious concrete containing the bone meal filter material, and the bone meal filter material comprises the following components in parts by weight: 70-80 parts of modified bone meal, 3-5 parts of attapulgite, 10-15 parts of cement, 2-4 parts of anhydrous sodium sulfate, 2-3 parts of gypsum, 1-3 parts of clay, 1-2 parts of fly ash, 1-2 parts of anorthite and 5-15 parts of water. The modified bone meal is prepared by grinding waste kitchen waste livestock and poultry bones and an activating agent and then modifying with a modifying agent, and the bone meal filter material is prepared by molding and sintering a green body raw material prepared by uniformly mixing the components. The bone meal filter material has an excellent adsorption effect on heavy metal ions, and the prepared pervious concrete has the advantages of alkali reduction, no vibration, heavy metal adsorption, self-compaction and the like.
本发明提供了一种骨粉滤料、其制备方法及包含其的自密实透水混凝土，骨粉滤料包括以下重量份的各组分：改性骨粉70～80份、凹凸棒土3～5份、水泥10～15份、无水硫酸钠2～4份、石膏2～3份、粘土1～3份、粉煤灰1～2份、钙长石1～2份，水5～15份，所述改性骨粉由废弃厨余畜禽骨头与活化剂研磨后经改性剂改性制得，所述骨粉滤料由上述各组分混匀制成的生坯原料经成型、烧结制得。该骨粉滤料对重金属离子具有优异的吸附效果，且制备的透水混凝土具有降碱、免振捣、吸附重金属和自密实等优点。
