Sound Insulation Property - an overview ScienceDirect

The sound absorption and insulation property of concrete improve with increasing CR content [88]. Concrete containing 20% CR can effectively isolate low-frequency sounds, such as railway trains that pass through tunnels at high speed, heavy trucks, tractors, helicopter and transformer substation [89] .
