Wybuch pandemii COVID-19 spowodował tragiczne konsekwencje dla zdrowia publicznego oraz zwiększył produkcję odpadów medycznych, które mogą przyczyniać się do dalszego rozprzestrzeniania wirusa, zagrażać zdrowiu obywateli oraz środowisku naturalnemu. W celu ograniczenia tych problemów zaproponowano metodę przetwarzania maseczek ochronnych, w sposób umożliwiający ich powtórne użycie podczas produkcji betonu. W artykule przedstawiono wyniki badań opisujące wpływ dodatku przetworzonego odpadu medycznego na właściwości zawierającego go betonu. Wyznaczono wytrzymałość na ściskanie i rozciąganie betonu sporządzonego z dodatkiem przetworzonych maseczek oraz betonu referencyjnego. Wykonano badania przepuszczalności właściwej przed i po ekspozycji na wysoką temperaturę w celu sprawdzenia, czy materiał otrzymany z recyklingu charakteryzuje się podobnymi właściwościami co stosowane włókna polipropylenowe. Dodatkowo wykonano badanie wpływu przetworzonych maseczek na ciepło hydratacji.

Alongside with all its difficulties and tragic consequences, the outbreak of the COVID-19 pandemic has also caused a drastic increase in the amount of the generated healthcare wastes. Healthcare wastes can accelerate the further spread of the virus and threaten the health of citizens and the environment. In order to deal with this lateral problem of the on-going pandemic, facemask wastes were processed and recycled in concrete materials. The objective of this research was to investigate the influences of recycled facemask products on the performance of concrete. To do so, the compressive and splitting tensile strength tests were performed to assess the mechanical behaviour of concrete with and without of the recycled facemask products. Moreover, gas permeability test was conducted on the designed samples before and after exposure to fire temperature, to verify whether the proposed addition provides a similar effect like conventional polypropylene fibres, or not. The results were supplemented with the heat of cement hydration measurements.
