Aging concrete in existing structures often suffers from changes in its properties as a result of continuous microstructural changes, such as reactions between the cement paste and aggregates, slow hydration and environmental influences that can cause degradation over time. These changes are not always detrimental, and the level of deterioration can be minimal if specifications are followed during the production of the concrete. However, the complex nature of the production and curing process, as well as the dependency on skilled workmanship often results in substandard quality concrete that has a tendency to degrade to undesirable levels over time. With the construction of these more complex structures, the overall aim of this paper is to evaluate the standard testing techniques used for a rapid non-invasive assessment of existing older concrete. The techniques from ACI228.1r-2003 and ACI22.2r-2013 are considere
