A controlled low strength material has constituents that include a cement, an aggregate, and a water. The aggregate includes concrete demolition waste. The controlled low strength material has a compressive strength that does not exceed 8.3 MPa, measured at 28 days. The controlled low strength material can alternately include a heavy oil fuel ash and the controlled low strength material can have a compressive strength that does not exceed 2.10 MPa, measured at 28 days.

Recycled concrete aggregates and heavy oil fuel ash for green controlled low strength material

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.

Utilization of heavy oil fly ash to produce controlled low strength material for backfilling applications

A well pad construction system includes a construction area, surface compaction equipment to compact the construction area, an excavator disposed at the construction area and movable to generate an excavated area, a cellar disposed in the excavated area, controlled low-strength material (CLSM), and backfill equipment disposed around the excavated area. The backfill equipment is moveable over the construction area to pour CLSM into a gap between the cellar and surrounding medium in the excavated area for holding the cellar in place and providing a firm well pad from which a rig may operate.
