The purpose of this experiment is to verify an efficiency of
repair for curting area.
The result of this experiment is the fact that the strength
of compression and bending in declined by width and depth
of curing area.
Deterioration of strength depends on depth to be repair area
and the strength of compression decreased up to 50% when the
repairing area is increased.
