Considerably different from sandstones, sands have point-like contact of grains. In contrast, sandstones have cementation between grains which has diminished the very narrow gap at contact of grains. In this paper, ultrasonic S-wave in brine-saturated glass beads and Ottawa sands is used to detect the very narrow space at contact of grains. The data of the dry beads/sands and brine are inputted into Biot theory to yield phase velocity of the saturated beads/sands.
