Ochrona zasobów naturalnych i efektywne zarządzanie odpadami, które mogą szkodzić naszemu środowisku, stanowi nie lada wyzwanie. Niniejsza praca poświęcona jest badaniu różnych właściwości betonu klasy M30, w którym kruszywo grube zostało całkowicie zastąpione dostępnym na rynku kruszywem ze spiekanego popiołu lotnego. Okazało się, że kruszywo to spełnia wymagania wytrzymałości docelowe betonu. W celu dalszej poprawy odporności na pękanie i wytrzymałości na rozciąganie zastosowano włókna bazaltowe. Dodatek włókien poprawił właściwości mechaniczne o około 3-4%. Badanie przepuszczalności chlorków przyspieszoną metodą i absorpcji wody wykazało, że trwałość betonu z kruszywa ze spiekanego popiołu lotnego mieści się w granicach normy.

Conservation of natural resources and effective management of waste materials that can harm our environment is a challenging phenomenon. This paper is focused to study the different properties of M30 grade concrete where the coarse aggregate has been completely replaced by commercially available sintered fly ash aggregate and it has proved to meet the target strength. To further improve the crack resisting behavior and tensile strength, basalt fibers was incorporated. The incorporation of fibers has improved the mechanical properties to around 3-4%. The RCPT and water absorption test has proved that the durability properties of sintered fly ash aggregate are within the standard specified.
