To recycle concrete, the concrete must first be broken and removed from the existing pavement—i.e., the demolition of concrete foundations, driveways, sidewalks, and other concrete structures. …
In steel-reinforced concrete (SRC) structures, it is difficult to separate or recycle steel and concrete using traditional demolition methods, which create a large amount of construction waste. A green and recyclable technology for demolishing SRC structures by induction heating (IH) is proposed in this study.
In such a context, recycled steel fibres (RSF) from waste tires have been considered as an alternative to the industrial steel fibres (ISF). This paper presents a …
In steel-reinforced concrete (SRC) structures, it is difficult to separate or recycle steel and concrete using traditional demolition methods, which create a large amount of construction waste.
In the present investigation, the RSF were added to concrete in two amounts: 39.25 kg/m 3 and 78.5 kg/m 3 to create the recycled steel fibre reinforced concrete (abbreviation used in the manuscript—FRC). According to the above-mentioned works, these amounts guarantee mixes in which fibres can be used to partially replace …
