摘要：
The objective of the REALight project is the development of a thermal process to produce lightweight aggregates in pilot scale and the implantation of a method to recover gypsum. Beside construction and demolition waste, various industrial by-products are studied as raw materials. The raw materials have so far been unused or used in applications with lower quality requirements. To prove the performance of the lightweight aggregates, their technical properties are tested and their use in different applications is studied, e.g., for lightweight mortars as well as lightweight concretes. The idea of producing lightweight aggregates from construction waste originated back in the 2000s. In the meantime, a process scheme has been developed in Weimar. Today, the results of a project show how these lightweight aggregates are produced on pilot scale and used in lightweight and infra-lightweight concrete as well as in repair mortars. image
