Aquarium test data are presented on commercially available ANFO and 7.5 wt % aluminized ANFO in 10-cm-i.d. clay pipe. The data obtained on the aluminized product show only sight measurable improvement in performance over the nonaluminized product, possibly because of inadequate control on initial sample density. Therefore, additional experiments were conducted on aluminized ANFO mixtures of our own composition to control initial sample density, aluminum concentration, and aluminum particle size. Direct measurement of shock pressures in the water were made with lithium niobate pressure transducers approx. 28 cm from the charge. These tests show that the addition of aluminum (average particle size < 100 ..mu..m) increases the peak pressure by more than 50% for the addition of 11 wt % aluminum to a standard (94/6) ANFO mixture. Tests conducted on 19 wt % aluminum showed a slightly smaller increase in peak pressure, indicating some optimal aluminum concentration for maximum shattering efficiency in blasting applications.
