Experimental Study on the Size Effect on the Probability Distribution of Concrete Compressive Strength by Youcheng Zhai

“…Compressive strength tests were performed on concrete cubic specimens with side lengths of 70 mm, 100 mm, and 150 mm, respectively. The Kolmogorov-Smirnov test results revealed that concrete compressive strength of each specimen size followed a normal probability distribution; that is, a change in specimen size did not affect the type of probability distribution. …”
