Sound insulation aggregate, preparation method thereof, sound insulation concrete and application of sound insulation concrete
The invention provides sound insulation aggregate and a preparation method thereof, sound insulation concrete and application thereof, and belongs to the technical field of building materials. The sound insulation aggregate provided by the invention comprises a silencing porous core, an elastic damping layer coating the surface of the silencing porous core, and a tough compression-resistant layer coating the surface of the elastic damping layer, the preparation raw materials of the silencing porous core comprise waste aerated concrete particles; the preparation raw materials of the elastic damping layer comprise waste elastic plastic powder, waste rubber powder and sawdust; and the preparation raw materials of the tough compression-resistant layer comprise dehydrated tailings, mineral powder, fly ash and fibers. The sound insulation aggregate provided by the invention realizes step-by-step continuous consumption of sound wave energy in a mode of combining the silencing porous core, the elastic damping layer and the tough compression-resistant layer, finally achieves the purposes of vibration reduction and sound reduction, and has a good noise reduction effect.
本发明提供了一种隔音骨料及其制备方法、隔音混凝土及其应用，属于建筑材料技术领域。本发明提供的隔音骨料包括消音多孔核芯、包覆在所述消音多孔核芯表面的弹性阻尼层以及包覆在所述弹性阻尼层表面的韧性抗压层；所述消音多孔核芯的制备原料包括废弃加气混凝土颗粒；所述弹性阻尼层的制备原料包括废弃弹性塑料粉、废弃橡胶粉和木屑；所述韧性抗压层的制备原料包括脱水尾料、矿粉、粉煤灰和纤维。本发明提供的隔音骨料利用消音多孔核芯、弹性阻尼层和韧性抗压层相结合的方式实现对声波能量逐级持续性的消耗，最终达到减振降声的目的，具有良好的降噪效果。
