Zusammenfassung
As concrete is large being used in acoustic screens construction, a deph knowledge of its acoustic properties may help to improve the design conditions of these kind of barriers. Incluiding a small percentage of porexpan pearls in the concrete core, the acoustic insulation of the screen is lightly improved. At Alfonso X el Sabio University laboratories, concrete barriers have been modelized with scaled models in order to analize the influence of material density in the acoustic properties of concrete.
