AB - While creating the sustainable construction systems it is crucial to innovate in production of construction materials by maximizing recycling and reuse of the materials during production and use of the buildings. The intention of this paper is to provide new insights and better understanding of sustainable oriented innovation in production of construction materials, in particular substitution of cement in mortar with waste material, fly ash, bearing in mind its huge negative impact on the environment. Previous investigations of possible use of fly ash have proven the possibility of its use for the production of cement for lightweight concrete, bricks, asphalt fillers, however the use of the fly ash in cement screeds was not considered.The aim of this work was to examine at first, justification of substitution of cement in mortar with fly ash due to its newly gained properties as change of density, compressive strength and water absorption. In order to take into account aspect of environmental protection the newly gained mechanical properties of the materials were tested in terms of its convenience for use in cement screeds.
