Reinforcement bar measurement in structural concrete using Ground Penetrating Radar method / Mohd Redzwan Mat Sah

Rebar diameter in structural concrete is an important parameter for a structural engineer to calculate the strength of certain construction. For construction, the critical area for structure is at beam, column and slab. At present only Radiography is the reliable and accurate non-destructive method...
