Lightweight sound-insulation aerated concrete block and preparation method thereof
The invention discloses a lightweight sound-insulation aerated concrete block and a preparation method thereof, and relates to the technical field of aerated concrete blocks. The polypropylene fibers are blended into the aerated concrete at a low mixing amount, so that the overall performance of the concrete is remarkably improved, the concrete is endowed with a new acoustic characteristic, and the polypropylene fibers have a unique physical property and a distribution mode; a structure similar to a natural or artificial fabric is formed in a pore network of the aerated concrete, when sound waves pass, tiny vibration of fibers can be induced, then the sound waves interact with surrounding pore walls, friction and energy conversion are generated, mechanical energy of the sound waves is effectively converted into heat energy in the process, and the sound waves can be effectively absorbed by the aerated concrete. The absorption and weakening of sound waves are realized, so that a remarkable sound absorption effect is shown.
本发明公开了一种轻质隔音加气混凝土砌块及其制备方法，涉及加气混凝土砌块技术领域。本发明通过将聚丙烯纤维以低掺量融入加气混凝土中，不仅显著提升了混凝土的整体性能，还赋予了混凝土新的声学特性，聚丙烯纤维以其独特的物理性质和分布方式，在加气混凝土的孔隙网络中形成了一种类似于天然或人造织物的结构，当声波通过时，能够诱发纤维的微小振动，进而与周围的孔隙壁产生相互作用，包括摩擦和能量转换，这一过程有效地将声波的机械能转化为热能，实现了对声波的吸收和减弱，从而展现出显著的吸声效果。
