Abstract

This paper presents the experimental result of testing machine and specimens factor on probability distribution of compressive strength of high strength concrete. It is clarified that the peak value of distribution is higher than the mean value of strength in high strength concrete, even if according to the testing method on JIS A 1108. It is clear that the peak of distribution is close to the mean value of strength and shape of probability distribution is close to normal distribution, when both sides of the specimen are grinded.
