The effect of the concentration of steel fibres on the properties of industrial floors
This paper presents the results of a series of experiments on samples made of steel fibre reinforced concrete. The investigated samples were made with different concentrations of steel fibres ranging from 20.0 to 32.5 kg/m3. Twenty-one cubic samples (15 x 15 x 15 cm) and fourteen cuboid samples (15 x 15 x 60 cm) were used for this investigation. The article focusses on the effect of the concentration of steel fibres on the properties of industrial floors. For this purpose, both destructive and non-destructive methods were used and compared. As a result of this study, it has been proved that compressive and flexural tensile strength are lower with increasing air content and decreasing density of concrete. Moreover, it was found that there is a correlation between ultrasonic pulse velocity and rebound hammer results which together can be used to estimate the compressive strength of steel fibre reinforced concrete.
Streszczenie
W niniejszym artykule przedstawiono wyniki serii eksperymentów wykonanych na próbkach z betonu zbrojonego włóknami stalowymi. Badane próbki zbrojone były różną zawartością włókien stalowych od 20.0 do 32.5 kg/m3. Do badań użyto 21 sześciennych (15 x 15 x 15 cm) i 14 prostopadłościennych (15 x 15 x 60 cm) próbek betonowych. W artykule skupiono się na zbadaniu wpływu zawartości włókien stalowych na właściwości posadzek przemysłowych. Do badań zastosowano i porównano metody niszczące oraz nieniszczące. W rezultacie udowodniono, że wytrzymałość na ściskanie i rozciąganie przy zginaniu zmniejsza się wraz ze wzrostem zawartości powietrza i malejącą gęstością betonu. Ponadto stwierdzono, że istnieje korelacja między wynikami ultradźwiękowymi i sklerometrycznymi, które mogą być wykorzystane do oszacowania wytrzymałości na ściskanie betonu zbrojonego włóknami stalowymi.
