The use of foam glass based aggregates for the production of ultra- lightweight porous concrete for the production of noise barrier wall panels

In the last few years, there is an increasing demand for hygienically harmless environment in the area of well-being. One of many hygiene limits is the reduction of unwanted noise, especially from road or rail traffic. Road and rail traffic poses a huge noise burden, mainly in the built-up areas and civil construction. Unwanted noise needs to be reduced (diverted, swallowed, deterred). The most common tool for noise elimination is construction of various types of noise barriers, embankments, silent road covers and other elements. The paper deals with the development of noise barrier wall panels using lightweight porous concrete with foam glass based aggregate in the absorber area. (C) 2019 The Authors.
