On the project

In the proposed research a new generation of innovative building materials - alkali-activated materials (AAMs), including geopolymers, will be developed with outstanding characteristics, reduced environmental impact, and adjusted to market needs in the Danube region. This new generation of cementitious materials, as an alternative to traditional cement and concretes, will utilize alkali-activated locally available industrial waste materials in Austria, Czech Republic and Serbia (such as fly ash and blast furnace slag). The focus of the research will be on understanding and characterizing the complex physical, mechanical, fracture mechanical and durability properties of the AAMs. The design, characterization and modeling of the material will represent the three major elements of the research. The durability of the developed materials will be carefully researched during the design process to ensure comparable life cycle performance. The objective is to optimize the composite achieving a good balance among its mechanical, fracture mechanical and durability performances.
