AB  - In this research, two non-destructive testing (NDT) methods, thermal vision analysis and image analysis, were implemented for monitoring the surface changes- erosion of mullite based ceramic samples in conditions of cavitation exposure. Thermal imaging analysis was focused on determining temperature line profile at the end of the cavitation experiment. Image analysis is a powerful tool for quantification of degradation level caused by different impacts and conditions. Based
on the results of image analysis, the degradation level during the testing was determined, as well as number of formed pits with their characteristics (average diameter and area). The results performed by both methods were discussed in order to obtain optimal procedure that should be followed for estimating degradation caused by cavitation erosion.

AB  - Establishing a wind park presents a complex enterprise, which involves numerous activities, often impossible to synchronize and drive into the appropriate time-frame. Therefore, in some cases, based on reasonable suspicion, a concern arises regarding the quality of already built components of structures. In such cases, the launch of suitable assessment procedures is required. Standards then define proper methods of in-situ assessment of concrete quality. Statistical methods are implemented in the analysis of the concrete components following the strict rules which, if executed correctly by the well-trained personnel of accredited institutions, provide exact and valid insight into the situation. This paper aspires to describe such a procedure on the basis of thorough in-situ investigation and the subsequent analysis. In this study, a large number of 255 core samples were taken from 17 wind tower concrete structure elements – foundations (out of 57 wind towers in total), and the compressive strength of already placed concrete was evaluated based on this set of results. The compressive strength is proved to be a good parameter for evaluating other aspects of concrete quality, mechanical properties, and durability.

AB  - The quantities of component materials used for production of concrete are high on the global scale, therefore alternative materials are experimented on, in order to replace the natural ones. The possibility of using ground waste sulfur from the oil refining (petroleum) industry as a filling component of self-compacting concrete is presented in the paper, based on common concrete laboratory tests. The physical and mechanical properties of selfcompacting concrete decrease to some extend due to use of ground sulfur, but this concrete remains useful for some building applications.
