Compressive Strength of Concrete Cores with Different Lengths
Publication: Journal of Materials in Civil Engineering
Volume 26, Issue 7
Abstract
Cores with diameters of 74 mm and length-to-diameter () ratios of 0.5, 1.0, 1.5, 2.0, 3.0, and 4.0, were removed from concrete beams. Compressive strength tests were conducted on 300 core specimens. The compressive strengths of concrete cores were fitted to the modified Weibull distribution. This information is useful in the theoretical description of concrete failure. Furthermore, on the basis of the Kolmogorov-Smirnov goodness-of-fit tests, the test data have been verified to follow this modified Weibull distribution. In addition, the modified Weibull model can predict the length effect more accurately than the conventional model.
