Sand Slurry is a self-compacting form of Controlled Density Fill (CDF) primarily used for filling tanks and large voids in excavation. A small portion of cement may be used in order to help firm up the mix and dissipate the large volume of water typically in the mix. As the name implies, it is generally all sand and water, with the occasional addition of cement and/or Fly Ash to make it pumpable. The PSF (lbs/square foot) of non-cementitious sand slurry is usually equal to that of the surrounding native soil.
