AB  - Implementation of statistical analysis for monitoring the formation and propagation of defects that occurred due to
exposure of the material to thermal shock and cavitation is presented in this study. Results of two groups of materials are
shown: refractory concrete sintered at three temperatures and ceramic materials based on cordierite and zircon. Aluminabased
refractory concretes were subjected to thermal stability test, while the surface morphological changes regarding the
defects were monitored after a certain number of thermal shock cycles. Cordierite and zircon based materials were initially
subjected to cavitation testing while after specified time periods, morphological changes in the surface defects were
analyzed. Besides the standardized methods, non-destructive testing of materials was applied for monitoring the surface
changes. Cameras, microscopes, and numerous software enable recording images of sample surface with appropriate
magnifications as well as monitoring and quantifying the surface damage degree with various image analysis tools. Thus,
this approach offers the quantification of selected morphological descriptors regarding the defects. Obtained values were
then subjected to pattern recognition method, the principal component analysis that can provide information on extracted
morphological descriptors by describing the main difference among observed defects and identifying variations among
them. As a result, a better insight into surface degradation that occurs during exposure to extreme conditions was obtained.
The multivariate analysis provided grouping and thus reduction of the descriptors while maintaining the highest
percentage of variance unchangeable. More precisely, the analysis extracted the most informative descriptors that should
be observed for monitoring changes in surface defects and determining a degradation mechanism.

AB  - Evironmetally safe mortars in which part of the cement binder was replaced by mineral
additives (i.e. zeolite, bentonite and fly ash) were designed. Fly ash, as fine powdery byproduct
of coal combustion, comprises heavy metals in its composition. Bentonite and zeolite are natural
adsorbents with ability to immobilize certain toxic elements and prevent their migration from the
mortar structure. In this study the ability of bentonite and zeolite to adsorb toxic cations present in fly ash leachate was investigated. Metallic cations were detected in quantities not higher than 52.6, 15.5, 52.4 and 22.7 mg/kg for Zn, Pb, Cu and Ni respectively. Adsorption kinetic was
monitored using 0.1 mol/dm3 solutions of each of investigated cations (Zn2+, Pb2+, Cu2+ and
Ni2+) as well as multicomponent solution of all these cations during predefined time intervals in
the range from 10-1440 minutes. Adsorption isotherms were obtained in concentration range for
each cation of single and multicomponent solution in the range from 0.10-0.30 mol/dm3. The obtained
results of this investigation indicate that bentonite and zeolite are efficient adsorbents and,
therefore, they can be applied in combination with fly ash in environmentally-safe construction
materials
