This thesis aims to propose a quality index on evenness of concrete floor groundworks. First, nine kinds of concretes were constructed as specimens under three grades of execution circumstances, measuring slump flow and finishability. Next, evenness of specimens were measured. Finally, as the quality index, relations between evenness and slump flow, finishability were shown in each of circumstances. The following are described from this index; 1. Using same concrete, execution circumstance greatly influences evenness. 2. Evenness is principally influenced by finishability, when the circumstance is upper. On the other hand, it is influenced by slump flow under poor circumstance.
