Abstract

The combined removal of steel and concrete during the removal of building structures is still
a challenge due to the different material properties and the resulting requirements on the cutting
tool. In this paper the authors will present a methodology, and its results, for enabling a
milling process for the machining of reinforced concrete. To identify the different mechanisms
taking place during cutting of the two materials concrete and steel, the machining of these
materials were studied separately. The aim of this investigation is to identify the dominant
wear mechanism and the process factors influencing the resulting cutting forces. Afterwards
the observations and conclusions will be assigned to the cutting of the material compound.
As influencing variables the size and form of the cross-section and the cutting speed were
investigated. Furthermore the benefit of a tool coating in milling concrete and reinforced concrete
was investigated.
