The chlorine concentration in chloride-contaminated FA cement concrete specimens was measured using a portable neutron generator based prompt gamma-ray neutron activation (PGNAA) setup with the neutron generator and the gamma-ray detector placed side-by-side on one side of the concrete sample. The minimum detectable concentration of chlorine in FA cement concrete measured in the present study was comparable with previous results for larger accelerator based PGNAA setup. It shows the successful application of a portable neutron generator in concrete corrosion studies.
► Portable neutron generator based PGNAA setup. ► PGNAA setup geometry suitable for chloride scan of concrete structure from outside. ► Chloride concentration measurement in fly ash concrete samples. ► Portable neutron generator based PGNAA setup performance comparable with larger accelerator based PGNAA setups.
