摘要
本文介绍了水泥基多孔吸声材料的主要性能评价参数及其作用机理,综述了国内外水泥基多孔吸声材料的研究现状,从材料组成和结构构造两方面论述了水泥基多孔吸声材料的性能及影响因素,并提出了未来的研究发展方向,水泥基多孔吸声材料具有优异的声学特性和力学性能,在降噪工程中有着广阔的应用前景。
In this paper,the main performance evaluation parameters and mechanism of cement-based porous sound absorbing materials have been researched.The research status of cement-based porous sound absorbing materials between domestic and abroad is introduced.The properties and influencing factors of cement-based porous sound absorbing materials are discussed from two aspects:material composition and structure,and proposed its future research direction.Because cement-based porous sound absorbing materials has excellent acoustic and mechanical properties,it has broad application prospects in noise reduction engineering.
