Application of Crushed Cement-stabilized sludge (Polynite) to Physical Barrier againat Termites
The ability of Coptotermes formosanus SHIRAKI tunneling into or passing through
the physical barrier using Polynite was examined
in the laboratory. And using globular glass
beads, the influence that the form of the
particles and the gap between particles influenced
to the penetration was examined. More, the
state of the workers carrying particles was
observed by the CCD micro color camera.
The device of the penetration test
The result of the penetration(Polynite)
40mm notes that the Polynite layer was penetrated by termites.
