Comprehensive method for determining the crack resistance of concrete
Incoming article date: 03.10.2020The results of scientific and experimental research on determining the width of the crack opening in concrete under the influence of mechanical load are presented. In the process of scientific research, a simultaneous complex measurement by tensometric and acoustic methods of the load of deformation, the width of the crack opening, the total count of acoustic emission was carried out to obtain complete diagrams of concrete deformation. As a result of the experiments, regression equations were obtained and the correlation dependence between the crack opening width and the total acoustic emission count was established.
Keywords: lightweight concrete, crack width, tensometric method, acoustic emission, deformation diagrams
