In Japan, large number of concrete structures were constructed in the high economic growth period (60's~70's), and they are entering a period over the designed service life, therefore the proper life cycle management for life extension of these structures is becoming necessary. The use of small diameter core specimen for compressive strength test in conducting the maintenance procedures for existing structures is desirable technology because it gives minor damage to the structure and less risk to cut off reinforcements when the core sampling is done. However, it is known that the variance of compressive strength test result by a small diameter core becomes large and it is difficult to evaluate precisely the compressive strength. From this background, the research described in this paper focused on development of the compressive strength test method by using small diameter core.
