The goal is the development of a dry mixture for lightweight cement composites for screeds while
maintaining the principles of Green Building Design in a combination of multi-criteria selection of
components in the mixture depending on the price, environmental impact and material
properties. The project is specific with regard to synergistic use of aggregates fraction 1/8 mm
based on expanded clay, foam glass and foam silicate based on construction and demolition waste
and partial replacement of part of cement using fraction 0/1 mm of construction and demolition
waste and secondary raw materials such as fly ash etc. Part of the solution will be the production
of mixes on the dry mix production line at the KNAUF. A set of material properties will be
determined for the resulting mixtures.
