Geothermal grout and method of using same to install a geothermal heating system
A thermally enhanced, single component, geothermal grout is composed of recycled materials including class F fly ash and cement kiln dust and is particularly useful as a grout mixture in filling a borehole in the ground for use in protecting a loop of a geothermal sytem. Additional components of the grout mixture can include a mid-range water reducer and a dry caustic material. The thermally enhanced geothermal grout can comprise a class F fly ash in a range of between approximately 50 to 80% by weight of the grout and cement kiln dust in a range of between approximately 20 to 50% by weight of the grout mixture.
