Sound proofing element made from textile reinforced concrete

摘要

Noise-protection element made of textile-reinforced concrete or another textile-reinforced binding agent is designed as a hollow case filled with sound-absorbent material. The large surface facing the sound has perforations (3). The reinforcement consists of fibers that are resistant to the binding agent. The element comprises longitudinal reinforcement consisting of individual rovings that are at least as long as the element and transverse reinforcement in the form of a textile mat. An independent claim is also included for the production of the above noise-protection element.
