“…The Prompt Gamma Neutron Activation (PGNAA) technique is a non-destructive technique and can be used to analyze bulk concrete samples [6][7][8][9][10]. Previously, the chloride concentration in blended cement concretes, such as FA, SF and BFS were measured utilizing the accelerator-based PGNAA setup at KFUPM [11][12][13].…”

“…This can be partly attributed to the unavailability of density information's of both polyethylene and 241 Am-Be neutron source used in this work. Nevertheless, sensitive calculations have been performed using different commercial values of these densities and the obtained results showed a maximum difference of 4% from the reference case (0.94 g/cm 3 for polyethylene, about 0.55 g/cm 3 for 241 Am-Be neutron source).…”

“…However, since reinforcement corrosion is caused by chloride ions, it is necessary to monitor their concentration. Other techniques, such as the Prompt-Gamma Neutron Activation Analysis (PGNAA) (Sowerby and Watt, 1994;Saleh and Livingston, 2000;Collico Savio et al, 1995;Khelifi et al, 1999;Tickner, 2000;Lim et al, 2001;Naqvi et al, 2003a-b;2004a) and X-Ray Fluorescence (XRF) technique (Sowerby and Watt, 1994), can be utilised to determine the elemental composition of bulk specimens.

Chloride-induced reinforcement corrosion is the principal cause of deterioration of concrete structures in the Arabian Gulf and the world over. Preventive measures against corrosion require maintaining the chloride and sulphate concentration in concrete below the threshold limits specified by the standards. This requires monitoring the chloride and sulphate concentration in concrete, and a nondestructive technique is preferable for this purpose. The Prompt-Gamma Neutron Activation Analysis (PGNAA) technique can be used to monitor the concentration of corrosive elements in concrete specimens. An accelerator-based PGNAA setup has been developed to measure the chloride and sulphate concentration in concrete. The PGNAA technique has been utilised successfully to measure the elemental composition of concrete. A.A. Naqvi et al.In this regard, several studies were undertaken to determine the calcium, silicon, chloride and sulphate concentration in the concrete specimens. Furthermore, the concentration of compounds, such as lime and silica was also determined. The results of these studies along with a description of the facility are presented in this paper.Reference to this paper should be made as follows: Naqvi, A.A., Nagadi, M.M., Garwan, M.A., Al-Amoudi, O.S.B., Maslehuddin, M., Khateeb-ur-Rehman and Raashid, M.
