Thus, the amount of waste and all the associated savings is to be reduced significantly.<\/p>\n<p>In this context, the project goal of a current research project is to reprocess the concrete waste in the precast plant into aggregates and return it to production and to develop an absorption concrete for noise barriers with the highest acoustic properties (concrete recycling).<\/p>\n<p>The technology development for grain processing and fractionation is intended to result in reproducible material development based on different grain compositions and in conjunction with acoustic measurement methods during production. The production of large-format demonstrators and the acoustic evaluation using the in-situ measurement method are the ultimate goal of the research project.<\/p>\n<p>The research project &#8220;Development of an absorption layer for concrete-based noise barriers made from 100% recycled concrete &#8211;
