Abstract: A critical review is made of selected aspects of the state-of-the-art of the prediction of performance of portland-cement concrete in service from the results of tests. The role of research in evaluating performance and in guiding the development of tests is discussed. It is concluded that while remarkable progress has been made, much remains to be done to provide basic and fundamental knowledge of the phenomena, the substances, and the environment of service. The critical needs are for better understanding of the nature and formation processes of the bonds that as formed give concrete strength, the processes by which these bonds become broken, and the critical levels of interacting environmental factors that produce irreversible changes in concrete in service. Such research results will permit the planning of experiments to yield data to establish relations between levels of relevant properties and performance in levels of environmental influences. From such relations, performance may be predicted. From such predictions, test methods and specifications may be established
