Abstract:

With the support of the Iowa Fly Ash Affiliates, research on reclaimed fly ash for use as a ; construction material has been ongoing since 1991. The material exhibits engineering ; properties similar to those of soft limestone or sandstone and a lightweight aggregate. It is ; unique in that it is rich in calcium, silica, and aluminum and exhibits pozzolanic properties ; (i.e. gains strength over time) when used untreated or when a calcium activator is added. ; Reclaimed Class C fly ashes have been successfully used as a base material on a variety of ; construction projects in southern and western Iowa. A pavement design guide has been ; developed with the support of the Iowa Fly Ash Affiliates.
