  • ADDITIVE TESTING FOR EARTH PRESSURE BALANCE

    1999-6-7 · Saturated sand was mixed with foam and the sand-water-foam mixture was removed with a screw conveyor. The mixing energy and the properties of the mixture in the screw conveyor have been studied. Results show that the permeability of a sand-water-foam mixture depends on the amount of pure water that remains in the mixture.
