水泥基复合多孔吸声材料的制备方法和性能

Preparation of Cement Based on Composite Porous Sound-absorbing Material and its Properties

以普通硅酸盐水泥、膨胀珍珠岩、陶粒主要原料,加以一定的辅助材料,研制出一种新型水泥基复合多孔吸声材料。该种材料具有吸声性能好、成本低、对环境无污染等优点。试验分析不同骨料、水灰比、骨料颗粒粒径对吸声性能的影响。结果表明,这些因素对其吸声性能影响明显。

A new cement was prepared which consisted of the composite porous sound absorbing materlal with portland cement, expanded perlite, ceramsite substances. That and non-pollution type of aggregate, material showed the characteristics of as main raw materials and some supplementary good sound absorption, low cost of preparation to the environment. The effect of some factors on the sound absorbing property, such as water to cement ratio and size of aggregate particles, was investigated experimentally.
