The feasibility of rock wool waste utilisation in a double-layer concrete brick for acoustic: a conceptual review

Denser population in a city leads to a serious noise pollution problem. In order to control the ambient noise effectively, a sound insulation brick is desired. However, conventional bricks have poor sound barrier system and is made from unsustainable materials that consume high energy. Hence, this p...
