Faced recently with a concrete cutting problem of formidable proportions, the Bowser-Morner Testing Laboratories of Dayton, Ohio, resorted to a technique the involved melting away the concrete. To do this, they used the powder lance process. In this process, aluminum and iron powder are burned in contact with pure oxygen to produce an extremely high combustion temperature of around 6000 degrees F. This high temperature combustion was used to melt both the concrete and the reinforcements bars because the molten material was being forced out of the cutting slot by the velocity of the flame. Bowser-Morner's experience seems to indicate that the powder lance process may be applicable to many concrete cutting problems. In this case over all costs were reduced, considerable time was saved, and a better end result was obtained than would have been possible if conventional methods had been employed.
