O projektu

Alkali-activated materials represent the future of the construction industry, especially due to processing of waste materials. Constructions from alkali-activated concrete can be exposed to various degradation processes (high and low temperatures, effects of water, chlorides, sulphates, acids and gases) that may adversely influence the internal or surface structure of the material. If alkali-activated concrete is exposed to such various degradation processes, its mechanical behaviour changes. The proposed project will deal with the use of non-destructive methods such as the acoustic emission method, impact-echo method and non-linear ultrasound spectroscopy for fast non-destructive testing of alkali-activated concrete that has been exposed to degradation processes. The results will subsequently be compared to the parameters obtained by thermogravimetric and differential thermal analysis, scanning electron microscopy, X-ray diffraction, flexural and compressive strength tests as well as density measurements.
