When raw ash: fly ash = 8.5:1.5, it had the highest pozzolanic activity. Melting occurred at 1250 °C when raw ash: fly ash = 8:2. With the increase of fly ash from coal-fired power plants, the melting phenomenon tended to be more evident at 1250 °C. At 1350 °C, the sample (raw ash: fly ash = 9:1) still did not melt.
