Abstract
A structural cellular grout, formed by combining grout and raw unprocessed road planings. The grout is formed by combining cement, pulverized fuel ash, and a liquid. The liquid comprises water and accelerating admixtures, retarding admixtures, water reducing or water proofing admixtures, and/or superplasticizers. The road planings are produced by grinding the surface of a road. A hardened mixture having a cellular structure is formed, without the use of a foaming agent, compaction, or agitation by mechanical equipment.
Claims13
A structural cellular grout comprising:
- cement pulverized fuel ash and road planings embedded in the grout, said road planings being produced by grinding the surface of the road;
- wherein the grout having a cellular structure is formed by mixing cement, pulverized fuel ash, a liquid, and the road planings, without the use of a foaming agent, and without the use of compaction or agitation by mechanical equipment, with the road planings and grout forming cells.
A method of forming a structural cellular grout, comprising the steps of:
- mixing together, without the use of a foaming agent, compaction, or agitation by mechanical equipment, cement, pulverized fuel ash, and a liquid to form a grout;
- adding raw unprocessed road planings to the grout to form a mixture, said road planings being produced by grinding the surface of a road;
- and
- allowing the mixture to harden to form a cellular structure, with the road planings and the grout forming cells.
