Relations between cracks in self-leveling material and quality of floor groundwork surface are experimentally examined. As the first stage, an influence of surface strength was examined intended for high-strength concrete. Then, it was clarified that surface strength was not quite large even using high-strength concrete, and cracks occurred easily when surface strength was small. Finally, relations between degree (length and width) of cracks and surface strength (width of a scratch, pull out strength, and shear strength) of floor groundwork were shown as examples of evaluation indexes about surface layer quality of concrete floor groundwork corresponding to defect in self-leveling material.
