Sound-absorbing ceramsite as well as preparation method and application thereof
The invention provides sound-absorbing ceramsite as well as a preparation method and application thereof, and belongs to the technical field of buildings. The sound-absorbing ceramsite disclosed by the invention has the characteristics of light weight, high strength, small and uniform pore size, low cost and the like; the bulk density is 600-1100 kg/m < 3 >, the roundness and sphericity are both greater than or equal to 0.8, the cylinder compressive strength is 5-10 MPa, the porosity is greater than 40%, the average pore size is 0.1-500 [mu] m, the apparent porosity is 5-65%, and the 1h waterabsorption rate is 5-35%. In the sound-absorbing ceramsite, more than 90% of the raw materials are industrial solid waste or building solid waste, the preparation cost is low, the sound-absorbing ceramsite is excellent in sound-absorbing performance, a high-performance ceramsite sound-absorbing plate or light-weight aggregate high-performance concrete can be manufactured, and an effective way is provided for resource utilization of the industrial solid waste and the building solid waste.
本发明提供了一种吸音陶粒及其制备方法和应用，属于建筑技术领域。本发明的吸音陶粒具有轻质、高强、孔径小且均匀、成本低等特点，堆积密度为600～1100kg/m，圆度和球度均≥0.8，筒压强度为5～10MPa，孔隙率＞40％，平均孔径为0.1～500μm，显孔率为5～65％，1h吸水率为5～35％。本发明的吸音陶粒中，90％以上的原料为工业固废或建筑固废，制备成本低，本发明的吸音陶粒吸音性能优异，可制作高性能陶粒吸音板或轻骨料高性能混凝土，为工业固废和建筑废料的资源化利用提供了有效途径。
