The objective of this work is to analyze the possibilities of reusing plastic waste of cables added in a plaster matrix. Firstly, the experimental process has allowed the physicochemical characterization of the raw material, plaster and plastic waste, consisting in elemental analysis, XRD and thermogravimetric analysis; Secondly, the performance of physicomechanical tests of the mixtures, Shore C hardness, absorption and resistance to flexion and compression. During the investigation, the water/plaster ratio of 0.8 was maintained, as well as the grain size of the plastic waste as it comes from the recycling factory (maximum 3 mm). On the contrary, the amount of added plastic waste has oscillated up to incorporate 50%, 60% and 70% over the weight of the plaster. In comparison to a reference sample, the obtained compounds are characterized by having a higher Shore C hardness, a lower absorption by capillarity and a decrease in their values of mechanical resistance. The addition of plastic waste to a plaster matrix can be considered as a possibility to obtain compounds of greater sustainability to be used in the field of sustainable construction.

Įmonės, teikiančios keleivių pervežimo paslaugas, siekia tapti prieinamos kiekvienam klientui. Internetinė svetainė – įrankis, padedantis ne tik populiarinti viešojo transporto idėją, bet ir lengvinti procesus. Straipsnio tyrimui atlikti pasirinktas Moustakis ir kt. (2004) internetinės svetainės kokybės vertinimo modelis. Tyrimas atskleidė, jog iš galimų 110 balų, analizuojama internetinė svetainė surinko 87. Tai nėra prastas rezultatas, tačiau internetinė svetainė turi tobulinamų funkcijų, kurios ateityje padės siekti aukščiausio rezultato.
