Another application of using fly ash is in [[roller compacted concrete]] dams. Many dams in the US have been constructed with high fly ash contents. Fly ash lowers the heat of hydration allowing thicker placements to occur. Data for these can be found at the US Bureau of Reclamation. This has also been demonstrated in the [[Ghatghar Dam]] Project in [[India]].
