| Research Abstract |
In this study, we developed gradually from a small device to a medium device to remove unburnt carbon from fly ash by ore flotation and checked the performance of the device by experiments. The conclusions are as follows. The medium device can effectively remove unburnt carbon from fly ash, and other elements in fly ash have not changed. The mechanical properties of concrete using the controlled fly ash slurry showed similar to that using fly ash specified type II per JIS.
