This report discusses the results of tests on concrete samples that were undertaken over a five-year period. A series of concrete samples was based on different cement types and cement contents. Solutions of contaminants were developed to simulate conditions found on contaminated land sites. The results of tests after five years show that the majority of test samples have been affected to some degree. A number of concrete samples were not considered resistant to high concentrations of contaminants and these generally performed poorly. However, concrete with higher cement content and combinations of resistant cements had better performance. Mechanisms for the chemical attack by contaminants are proposed and a risk based approach to the use of concrete in contaminated land is discussed.
