Abstract : |
Prompt gamma neutron activation analysis (PGNAA) technique has been used to determine lime/silica ratio ill concrete samples using an accelerator-based PGNAA facility. The ratio was determined from the measured yield of 6.42 MeV prompt gamma-rays of calcium and 4.93 MeV gamma-rays of silicon from the six concrete samples. The experimental results were compared with the results of the Monte Carlo simulations. An excellent agreement has been achieved between the two. The study has demonstrated successful use of the accelerator-based PGNAA setup in non-destructive analysis of the concrete samples. (c) 2005 Elsevier B.V. All rights reserved., |
