also held constant. Furthermore, a high-power microwave generator pro-
viding power of up to 25 kW at a frequency of 2.45 GHz was used. All the
experiments were performed inside a closed copper screen room used for
containing microwave energy. The results of the experiments showed that
microwave heating can significantly increase the penetration depth rates of
the mechanical tools in selected types of hard rock.
3.5 CONFIGURATION OF MICROWAVE- ASSISTED
SELECTIVE DEMOLITION TOOLS
A number of available microwave-assisted selective demolition technologies
(applicable to concrete demolition) were reviewed in the previous section.
Microwave-assisted equipment will be discussed next.
