Past and Future of Concrete Quality Evaluation

This paper examines the current practice, the recent developments, and the future prospects of various methods and techniques used for the quality evaluation of representative concrete and in-place concrete. Special attention is given to trends that will dominate the field in the future. Recent advances in accelerated test methods, ultrasonic testing, radioactivity methods, probe tests, pull-out tests, and rapid analysis of fresh concrete have been reviewed. The maturity concept, and its future role in the evaluation of concrete quality are mentioned. There is a great potential in the concrete industry for accelerated test methods and various nondestructive and partially destructive methods of testing in-place concrete.
