Ball milling of fresh fly ash up to 60 h reduced its size by a magnitude of 405 times to 148 nm. The specific surface area has increased from 0.249 m 2 /gm for fresh fly ash to 25.53 m 2 /gm for fly ash ball milled up to 60 h. The increase in surface area has been found to be more than 100 times in magnitude. Figure 1

Fly ash is a pozzolan, a substance containing aluminous and siliceous material that forms cement in the presence of water. When mixed with lime and water, fly ash forms a compound similar to Portland cement. This makes fly ash suitable as a prime material in blended cement, mosaic tiles, and hollow blocks, among other building materials.
