Abstract
Embodiments of a dry mix for producing a concrete composition are provided. The dry mix includes aggregate, cement, and bed ash. The bed ash contains the combustion product of a fluidized bed coal combustion reaction. Additionally, embodiments of a method of preparing the dry mix and embodiments of a method of preparing a concrete composition are provided. The dry mix is also suitable for repairing soil slips, and embodiments of a method of repairing a soil slip are also provided.
Claims21
A dry mix, comprising:
- aggregate;
- cement;
- and
- bed ash;
- wherein the bed ash comprises a combustion product of a fluidized bed coal combustion reaction;
- and
- wherein the cement and the bed ash are premixed such that the cement coats the bed ash.
A dry mix, comprising:
- aggregate;
- cement;
- and
- bed ash;
- wherein the bed ash comprises a combustion product of a fluidized bed coal combustion reaction;
- wherein the fluidized bed coal combustion reaction involves high-sulfur coal;
- and
- wherein the combustion product has been post treated with quicklime.
A dry mix, comprising:
- aggregate;
- cement;
- bed ash;
- and
- fluorite;
- wherein the bed ash comprises a combustion product of a fluidized bed coal combustion reaction.
A method of preparing a dry mix, comprising the steps of:
- providing bed ash and cement, the bed ash comprising a combustion product of a fluidized bed coal combustion reaction;
- mixing the cement and the bed ash;
- and
- adding aggregate to the mixed cement and bed ask;
- wherein the mixing step is performed until the cement coats the bed ash.
A method of preparing a concrete composition, comprising the steps of:
- providing a dry mix, the dry mix comprising:
- aggregate;
- cement;
- and
- bed ash, the bed ash comprising the combustion product of a fluidized bed coal combustion reaction;
- mixing the dry mix with a fluid containing water to form a wet concrete;
- and
- allowing the wet concrete to cure;
- wherein the mixing step is performed in a mud hole.
A method of preparing a concrete composition, comprising the steps of:
- providing a dry mix, the dry mix comprising:
- aggregate;
- cement;
- and
- bed ash, the bed ash comprising the combustion product of a fluidized bed coal combustion reaction;
- mixing the dry mix with a fluid containing water to form a wet concrete;
- applying the wet concrete to an underground road or to a hole in an underground road;
- allowing the wet concrete to cure.
