    摘要： The invention relates to a method for producing expanded glass granules. To this end, starting materials are provided, comprising 80% to 95% glass and 5% to 20% sodium silicate hydrate having a water of crystallization content between 1 and 2 wt%, in relation to the solids content. After the glass is ground, the starting materials are mixed, the ground starting materials are granulated into raw granules, and the raw granules are mixed with a release agent, the mixture comprising the raw granules and the release agent is heated to a processing temperature. In a first partial step, the pores on the surfaces of the particles of the raw granules are closed, and in a second partial step, the water of crystallization is dissolved from the sodium silicate hydrate and caused to thermally expand, whereby the particles of the raw granules expand and form the expanded glass granules. The invention further relates to expanded glass granules comprising loose expanded glass particles, the majority of which consists of glass, have expanded cavities, comprise a densely sintered surface made of glass and exhibit water absorption of less than 10%. Finally, the invention relates to the use of such expanded glass granules as an additive in mortar or as a filler in rinsing liquid.

    摘要： The invention relates to a noise-absorbing component, in particular for outdoor use, comprising a noise-absorbing cover layer (03) and noise absorbers (06) which are embedded into the cover layer and which have an increased degree of absorption compared to the cover layer (03). The cover layer surface, which is oriented in the direction of the noise source, is flat, and the noise absorbers (06) are mutually spaced. An open absorption surface of the noise absorbers lies on a plane parallel to the surface of the cover layer, and the surface area which is occupied by the noise absorbers (06) is smaller than the surface area which is not occupied by the noise absorbers on said plane. The invention also relates to a noise-protection wall comprising a support layer (02) and numerous noise-absorbing components attached to the support layer.
