The invention discloses a heavy-cement-based sound absorption and insulation board which comprises a sound absorption and insulation board body, the sound absorption and insulation board body is prepared from a geopolymer cementing material, and the geopolymer cementing material is composed of geopolymer, machine sand with the particle size of 0.315-5 mm), polyester fiber ribs (A) and an excitant.The board has the beneficial effects that the geopolymer is a tailing natural waste material rich in silicon and aluminum, and achieves cyclic utilization of power plant and mine field waste treatment; meanwhile, the geopolymer has a zeolite-like phase, can be used for sealing radioactive hazardous substances and can be used for sealing nuclear wastes, so that the anti-radiation effect of the sound absorption and insulation board is improved; the board can be applied to a roadbed sound barrier (large-span sound absorption and insulation components), is suitable for being applied to a roadbedsound barrier plate, and plays a positive role in resisting the wind load of a screen body; a secondary sound wave refraction plane is arranged on the inner wall of the plate surface hole, so that refraction and interference resistance loss of sound wave length are effectively increased; and through the designed fixing mechanism, rapid installation of the sound absorption and insulation board bodyis achieved.
本发明公开了一种重型水泥基吸隔声板，包括吸隔声板本体，所述吸隔声板本体由地质聚合物胶凝材料配制而成，其中材料组成分别为：地质聚合物、机砂(粒径0.315‑5mm)、聚酯纤维筋(A)、激发剂；本发明的有益效果是：地质聚合物为富含硅铝的尾矿天然废弃物资，对电厂、矿场废弃物处理起到了循环利用；同时地质聚合物具有类沸石相，具有封存放射危害物质，可以用于封存核弃物，增加了吸隔声板防辐射的效果；在路基声屏障中可以应用(大跨度吸隔声构件)，适合应用路基声屏障板，对屏体风荷载起到了积极抵抗作用；在板面孔内壁具有二次声波折射平面，有效增加声波长的折射、干涉阻耗；通过设计的固定机构，实现了吸隔声板本体的快速安装。
