some advantages of these techniques are:
- The two
techniques here presented are especially useful to break big blocks, and are an
easy-to-use alternative to explosives and heavy machinery.
Contrary to explosives and heavy machinery (tilt-hammer and bulldozer) these
techniques do not transmit shock vibration to the fossils, thus they are
suitable for paleontological excavations.
Stone-splitters and expansive demolition agents are very easily portable
contrast to explosives, there is no need of special authorization, for either
stone-splitters or expansive demolition agents.
associated with these techniques are – relative to explosives or bulldozers –
environmental costs – contrarily to explosives, for example.
- In low
temperature circumstances the expansive demolition agent the expansion stresses
are much lower.
application process of expansive demolition agents require more time than
Stone-splitters and/or expansive agents can also be used on a small scale to
make precise fractures where they are desired. In laboratory preparation where
noise- and or dust-pollution can prevent hard hammering or sawing, these
techniques are potentially useful.
