Reduction in Bentonite-Based Grout Concentration in Grout Fluids

摘要

Bentonite-based grout fluids and methods of using the grout fluids are provided. A method of using a grout fluid includes placing a geothermal conduit in at least one hole in the earth, providing a grout fluid including a bentonite-based grout at a concentration of about 15 pounds to about 25 pounds of bentonite-based grout per about 11.5 gallons (e.g., 12 gallons) to about 27 gallons of water, and introducing the grout fluid into the at least one hole adjacent to the geothermal conduit.
