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.

Cementitious compositions and methods of making and using

The present invention provides a packaged cementitious product including a bag formed of a polymeric material. The bag has first and second sealed ends. The first end has a first tab extending therefrom defining at least one aperture therethrough so that the first tab defines a first handle. The second end has a second tab extending therefrom defining at least one aperture therethrough so that the second tab defines a second handle. A cementitious product is sealed within the bag, and wherein the first and second handles facilitate the handling of the packaged cementitious product.

Packaging for particulate and granular materials

The present invention provides a method of beneficiating slag, including mixing the slag with water to form a slurry. The slurry is screened through a first screen to remove a first portion of material and then screened through a second screen to remove a second portion of material. In one embodiment, the second portion of material has a carbon content less than about 5% and, more preferably, a carbon content less than about 1%.
