Includes bibliographical references (leaves 131-135). Restrained shrinkage in bonded concrete overlays can cause stress build up, cracking and even debonding. Tensile relaxation is the main mechanism of stress relief in concrete overlays. This results in less possibility of cracking and debonding. The research described in this study presents an analytical method of analysis. This method is based on tests performed to assess tensile relaxation in concretes subjected to restraint. Although this study is limited in scope, it serves as an introduction to the topic and contributes a valuable bank of results obtained. In this study, commercial repair mortar (Sika® Rep LW), 0.45 and 0.65 w/c ratio custom-made mixes were investigated. Uniaxial tensile strength, tensile elastic modulus, shrinkage and tensile relaxation tests were done on dog-bone concrete mortar specimens. 2015-01-13T03:48:17Z 2015-01-13T03:48:17Z 2009 Master Thesis Masters MSc http://hdl.handle.net/11427/12109 eng application/pdf Department of Civil Engineering Faculty of Engineering and the Built Environment University of Cape Town |
