Flexural Performance and Reflective Cracking Behavior of Repair Systems Produced with High Early Strength Cementitious Composites

In this study, new generation high early strength repair materials compatible with the existing concrete substrate were produced without compromising increased ductility and multiple micro-cracking behavior and the performance of these repairs was compared with a commercially available high early strength repair material. In the first section of the study, basic mechanical properties of monolitically tested mixtures were assessed. In the second section, usability of mixtures produced in the layered state as a repair material was investigated by focusing on flexural performance and reflective cracking behavior. HESECC mixtures produced herein adequately satisfied the early age mechanical properties expected from a certain repair material and layered specimens which significantly minimized the propagation of reflective cracking exhibited relatively higher ductility compared to REP material widely used and available in the related markets
