Abstract

This study investigated experimentally and analytically changes in the cracking resistance of self-consolidating concrete at an early age. Wedge-splitting tests were performed with four different SCC mixes at 1, 2, 3, 14, and 28 days. Softening curves that optimally fit the measure load-CMOD curves were found by inverse analysis. Using the results of the tests and inverse analyses, we examined how fracture energy and four parameters of bilinear softening curves vary at early ages, and on this basis we suggest a model for determining the effects of age on the softening curve.
