Development of a 2nd Generation Neutron-Based Detector for Chloride in Concrete

TRB’s Highway Innovations Deserving Exploratory Analysis (IDEA) has released Highway Project 136: Development of a 2nd Generation Neutron-Based Detector for Chloride in Concrete that provides details of an advanced nondestructive test instrument for measuring chlorides in concrete. The test method is based on prompt gamma neutron activation and may enable more regular nondestructive inspections of bridges and structures for possible risk of chloride-promoted rebar corrosion.

The NCHRP Highway IDEA program is part of the National Cooperative Highway Research Program (NCHRP). The program is sponsored by the member states of the American Association of State Highway and Transportation Officials.
