Abstract
A cementitious composition is provided that comprises an effective amount of bottom ash and an effective amount of cement. In one embodiment, a structural product formed from mixing the composition with an effective amount of water has a seven-day compressive strength of at least about 2,500 psi and, more preferably, a seven-day compressive strength of at least about 4,000 psi. In another embodiment, a structural product formed from mixing the composition with an effective amount of water has a twenty-eight-day compressive strength of at least about 4,000 psi and, more preferably, a twenty-eight-day compressive strength of at least about 5,000 psi.
