Abstract

Although fly ash is commonly used as an additive to cement, large amounts of this material are disposed in landfills. To mitigate, it would be interesting to develop new products in which fly ash can be easily used and required in large quantities. In this work, fly ash is added to manufacture eco-friendly materials with acceptable acoustic and non-acoustic properties and a low cost. We built a barrier composed of fly ash (60 wt.%), type II Portland cement (25 wt.%), vermiculite (14.5 wt.%) and polypropylene fibers (0.5 wt.%). The barrier complied with the mechanical requirements of European standards. The sound absorption coefficient and the airborne sound insulation were determined in a reverberation room, and the barrier was classified as A2 and B3. No leaching problems were observed.

粉煤灰降噪屏障的实验研究

尽管粉煤灰通常被用作水泥的添加剂，但大量的这种材料被丢弃在垃圾填埋场。为了缓解这种情况，开发新产品是很有意思的，因为飞灰可以很容易地使用，并且需要大量使用。在这项工作中，粉煤灰被添加到制造具有可接受的声学和非声学特性且成本低的环保材料中。我们建造了一个由粉煤灰（60wt%）、II型硅酸盐水泥（25wt%）、蛭石（14.5wt%）和聚丙烯纤维（0.5wt%）组成的屏障。该屏障符合欧洲标准的机械要求。在混响室中测定了吸声系数和空气中的隔声量，并将屏障分为A2和B3。未发现浸出问题。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
