Non-traditional Non-destructive Testing of the Alkali-activated Slag Mortar during the Hardening

Popis výsledku v původním jazyce

This paper reports the results of measurements during hardening and drying of specimens of alkali-activated slag mortars. Alkali activated slag is a material having a great potential to be used in practice. The main drawback of this material is a high level of autogenous and especially drying shrinkage, which causes a deterioration of the mechanical properties. The aim of this paper is introduce the effect of method treatment of mortars and time curing on the microstructure of alkali activated slag mortars. An understanding of microstructure performance relationship is the key to true understanding of material behaviour. The results obtained in the laboratory are useful to understand the various stages of micro-cracking activity during the hardening process in quasi-brittle materials such as alkali-activated slag mortars and extend them for field applications. Non-destructive acoustic analysis methods, Impact-echo method as a traditional and the Acoustic emission method as non-traditional method for civil engineering were used for experiment. The principle of the Impact-echo method is based on analysing of the response of an elastic-impulse-induced mechanical wave. Acoustic emission is the term for noise emitted by material and structures when they are subjected to stress. Types of stress can be mechanical, thermal or chemical. Ultrasound testing and loss in weight were used as complementary methods for the tested samples.
