UTILIZATION OF HEAVY OIL FLY ASH TO PRODUCE CONTROLLED LOW STRENGTH MATERIAL FOR BACKFILLING APPLICATIONS

摘要

A controlled low strength material has constituents that include a cement, an aggregate, a heavy oil fly ash, and a water. The controlled low strength material has a compressive strength in a range of 300 kPa to 2.1 MPa. In certain embodiments, the heavy oil fly ash can be part of a heavy oil fly ash slurry.
