Grading and valuing standards of assessment index .

Grades Value Damage state

I0.0~0.1Loud sound, hammer leaves no trace on the surface.
II0.1~0.25Loud sound, hammer leaves obvious traces on the surface.
III0.25~0.5Dull sound, the concrete is smashed, and traces are left on the surface.
IV0.5~0.8Dull sound, the concrete is smashed and dented.
V0.8~1.0The sound is weak; the concrete exfoliates significantly.
